Whether you’re looking to breathe new life into an old laptop, build a career in tech, or simply escape software licensing fees, Linux offers compelling advantages. Android phones, cloud infrastructure, smart devices, and most of the internet all run on Linux. This guide covers the top reasons why Linux might be the right choice for you.
What is Linux?
Linux is a free, open-source operating system kernel, the core part of the operating system created by Linus Torvalds in 1991. When people talk about “Linux,” they’re usually referring to a Linux distribution (or “distro”), which bundles the kernel with software, a desktop environment, and tools to create a complete operating system, such as Ubuntu, Linux Mint, Red Hat Enterprise Linux, and Kali Linux.
Unlike Windows or macOS, Linux isn’t controlled by a single company. Thousands of developers worldwide contribute to its development, resulting in hundreds of distributions tailored for different needs.

Security and privacy advantages
The average user wouldn’t think of running Windows without malware and virus protection. Just about every business in the world requires some type of virus protection software for all of their Windows devices. And macOS is not immune to viruses either, as we have seen in recent years.
Linux is simply more secure. That doesn’t mean it’s invulnerable to hacking attempts. It’s just that the design of Linux’s architecture makes it significantly harder to compromise than other operating systems.
Key security features of Linux:
- Permission-based architecture that limits what programs can access
- No administrator access for regular users by default, reducing the risk of system-wide damage
- Package signing and trusted repositories that verify software authenticity
- Open-source code that thousands of developers review for vulnerabilities
- Fewer malware targets since most malware is written for Windows
Security professionals rely on Linux for their work. Kali Linux, for example, comes loaded with penetration testing and network security tools that professionals use to identify vulnerabilities in systems.
Why organizations trust Linux
Linux’s security credentials extend to the highest levels. The US Department of Defense uses Linux on security-critical systems and supercomputers. Major cloud providers including Amazon Web Services, Microsoft Azure, and Google Cloud support Linux extensively across their cloud platforms.
When organizations handling sensitive data consistently choose Linux, it speaks to the operating system’s reliability and security. Even Microsoft, which built its business on Windows, chose Linux to power Azure Cloud Computing Services.

Cost benefits and open source freedom
Linux is and always has been available to everyone for free. Unlike Windows, which has always cost money, or macOS, which requires expensive Apple hardware, Linux can be downloaded and installed on virtually any computer at no cost.
The cost benefits extend beyond the operating system itself:
- No license fees for the operating system
- No required subscription costs for most community Linux distributions
- Access to thousands of free, open-source applications
- Freedom to try different distributions without financial commitment
- Significant savings for startups, small teams, and enterprises
What open source means for you
Linux is open-source software, meaning the source code is available to the general public under the GNU General Public License (GPL). Anyone can download, modify, and even create their own version of Linux.
If you’re not a programmer, this might not seem relevant, but it really should. Because of Linux’s open-source licensing, thousands of distributions exist, each with custom features that wouldn’t be possible with closed-source code. This model also means thousands of developers constantly work to improve security, fix bugs, and add features. Updates happen quickly, and the community catches vulnerabilities faster than any single company could.
Stability, performance, and hardware flexibility
The Linux operating system is very stable, reliable, and less prone to crashes than other operating systems. Even Microsoft chose Linux as the operating system to power their Azure Cloud Computing Services instead of their own Windows Server operating system.
In using Linux, you’ll notice that your computer runs just as fast after years of use as when you first installed the operating system. With Windows, you often have to defragment the hard drive periodically and may even need to reinstall the operating system to restore performance.
Linux maintenance is simple. Each distribution has a large community of open-source developers who make improvements, fix bugs, and increase security constantly. A single command or click can install updates, and most updates complete without requiring a reboot.
Linux runs efficiently on a wide range of hardware:
- Old laptops and desktops that can’t handle modern Windows
- Raspberry Pi and other single-board computers
- Enterprise servers requiring maximum uptime
- Embedded devices like routers and smart TVs
- Supercomputers requiring peak performance
Why Linux runs faster on older hardware
The core Linux operating system is very lightweight and makes efficient use of system resources. Windows comes with drivers for all supported hardware in one package, which is why it must deprecate certain hardware periodically. Linux is customizable, allowing users to choose only the drivers and features they need.
Some lightweight Linux distributions can run on very low system requirements compared with modern Windows.
Customization and choice
You can configure some things on Windows or Mac, like changing your desktop background. But is configuration the same as customization? In short, no.
With Linux, you can change out the entire desktop environment. You have the choice between GNOME, KDE, Cinnamon, and other desktop systems. You can choose from half a dozen different shell systems if you work on the command line. And if you want, you can switch to a completely different Linux distribution.
Popular distributions for different needs:
- Ubuntu and Linux Mint: Beginner-friendly with familiar interfaces
- Red Hat Enterprise Linux: Enterprise-grade with commercial support
- Kali Linux: Security tools for penetration testing professionals
- Arch Linux: Maximum customization for advanced users
- Android: Mobile operating system built on the Linux kernel
Because of Linux’s open-source nature and GPL license, many different distributions of Linux are available depending on the type of features you need. Linux doesn’t come with bloatware, and as you install it, you can pick and choose which features you need, which you don’t want, and which you want disabled.
Software, applications, and use cases
Linux users have a lot of choices when it comes to software, and much of it is free to use. LibreOffice is an office productivity suite containing word processing, spreadsheet, presentation, drawing, database, and formula tools.
You can browse the Linux software center and find free software for all of your business and personal needs. Common tasks have excellent Linux alternatives:
| Task | Linux Software |
| Office productivity | LibreOffice, OnlyOffice |
| Web browsing | Firefox, Chrome, Brave |
| Thunderbird, Evolution | |
| Photo editing | GIMP, Darktable |
| Video editing | Kdenlive, DaVinci Resolve |
| Music production | Audacity, Ardour |
Gaming on Linux
Linux gaming has improved dramatically in recent years. Steam’s Proton compatibility layer allows thousands of Windows games to run on Linux with minimal configuration. The Steam Deck, Valve’s popular handheld gaming device, runs on Linux.
Many games now have native Linux versions, and the library continues to grow. While not every game works perfectly on Linux, the situation improves constantly. For casual gamers and many serious players, Linux gaming is now a viable option.
Linux for developers and programmers
While the average computer user may think the command line is the realm of hackers, software developers use it daily. The Linux terminal gives developers more power over their operating system than the Windows shell does.
Many Linux distributions include or make it easy to install programming languages like Python, Ruby, PHP, and C. Linux also offers:
- Native support for Docker and containerization
- Easy installation and use of Git for version control
- Package managers for easy dependency management
- A development environment that matches most production servers
Since most web servers run Linux, developing on Linux means your local environment matches where your code will actually run.
Community support and resources
Linux’s reach is huge. A big percentage of servers run Linux. Most system administrators and developers know Linux. That means a lot of people are willing to help newcomers on help forums and sites like StackOverflow.
Support resources for Linux users:
- Distribution-specific forums (Ubuntu Forums, Linux Mint Forums)
- Stack Overflow and Unix Stack Exchange
- Reddit communities (r/linux, r/linuxquestions)
- Built-in documentation (man pages and info pages)
- Official documentation for each distribution
- Paid enterprise support for business users
Linux was designed from the ground up to be helpful to users. Built-in command line utilities provide documentation on libraries, commands, standards, and other features. Many common questions you have will usually get answered quickly by someone who has run into the same issue.
Where Linux runs today
When it comes to desktop operating systems, users may argue about whether Windows, macOS, or Linux is best. But when it comes to running servers, there is no argument. Linux is king.
Linux powers the infrastructure you use every day:
- Most web servers and cloud infrastructure
- Android phones and tablets (over 70% of mobile devices)
- Smart TVs, routers, and Internet of Things (IoT) devices
- Supercomputers (all of the top 500 supercomputers run Linux)
- Cars, medical devices, and industrial systems
- Raspberry Pi projects and maker devices
For servers, Linux is free, lightweight, and customizable to run efficiently on any hardware. This proven track record across billions of devices demonstrates Linux’s reliability and versatility.
Getting started with Linux
Current distributions of Linux are very user-friendly. You can install and use Linux without ever touching the command line if you want. Linux has many great graphical user interfaces that allow new users to do many everyday tasks they could do in Windows or Mac.
Getting started is straightforward:
- Choose a beginner-friendly distribution (Ubuntu or Linux Mint recommended)
- Download the ISO (disc image) file from the distribution’s website
- Create a bootable USB drive using free tools like Rufus or Etcher
- Boot from the USB to try Linux without installing anything
- If you like it, follow the graphical installer to set up Linux
You can also dual-boot, keeping Windows alongside Linux and choosing which to use at startup. This lets you transition gradually while keeping access to Windows software you might still need.

Challenges and considerations
Linux isn’t perfect for everyone, and it’s worth understanding the challenges before making the switch.
- Learning curve: If you’ve used Windows your entire life, Linux will feel different. While modern distributions minimize this with familiar interfaces, some adjustment is required. The good news is that basic tasks work similarly, and you can learn advanced features over time.
- Software compatibility: Some proprietary software doesn’t have Linux versions. Adobe Creative Cloud, Microsoft Office (though web versions work), and certain specialized professional software may not be available. However, alternatives exist for most common applications.
- Gaming limitations: While Linux gaming has improved dramatically, some games still don’t work or require extra configuration. Anti-cheat software in competitive games can be problematic. If gaming is your primary use, research compatibility for your specific games.
- Hardware drivers: Most hardware works out of the box, but some specialized devices (certain printers, webcams, or Wi-Fi adapters) may lack Linux drivers. Checking hardware compatibility before switching is wise.
These challenges are real but manageable. Most users find that the benefits outweigh the learning investment.
