If you have an old PC in the closet (the one from 2014, the one your kid took to college, the one you stopped using when it got too slow), there's a real option that most people aren't even aware of.
You can put Linux on it. It will run fast. It will be safe. And for the right kind of user, it'll be the best $0 computer in the house.
What Linux actually is
Linux is a different operating system. Same role as Windows or macOS. It's what your computer uses to run programs, manage files, and connect to the internet. It's just made by a different group of people, with different priorities. It is the most widely used operating system, powering most of the internet, most industrial systems, and almost every device you use, other than your Windows PC or Apple Devices. Android, which powers the majority of phones and tablets worldwide, is a Linux-based system. ChromeOS, the operating system on Chromebooks, is also linux-based.
The two things that matter for you:
It's free. No license, no purchase, no subscription.
It's lighter. A computer that struggles with Windows 11, or even Windows 10, will usually feel snappy with the right version of Linux. Old hardware that felt obsolete can feel new again.
The trade-off is that some of what you do today won't work the same way on it. We'll get to that.
Who Linux is right for
The honest filter, in order of importance:
You do most of your computing in a web browser. This is the biggest one. Email, banking, social media, video streaming, shopping, news: if 90% of your computer use is just "open a web browser and do things," Linux is going to feel almost identical to what you have now. Same Gmail, same Facebook, same YouTube, same banking site. You won't notice you're on a different OS most of the time.
You don't depend on specific Windows programs. Microsoft Office desktop apps don't run on Linux. (The web versions of Office do, and they work fine for most home users.) Quicken doesn't run on Linux. Some specialty hobby software doesn't. If you depend on any of those, this isn't the path for you.
You don't play modern PC games. Linux gaming has improved a lot, but if "gaming" is a meaningful part of your computer time, get something else.
You're not afraid of a small learning curve. Things look different. Some menus are in different places. Installing software works through a "software store" but a different one than you're used to. It isn't hard. It is different. You need to be patient with that for the first few weeks.
You want something that lasts. Linux on the right machine will run reliably for years longer than that same machine would running Windows.
If those five things describe you, this is a real option. If even one of them is wrong, especially the second one, pick a different path.
A specific honest case
Here's the kind of person Linux is perfect for:
A retiree, on a 9-year-old Dell laptop, who uses the computer for email, the local newspaper, online banking, video calls with grandkids, and looking at family photos. Windows feels slow. Buying a new computer feels expensive and unnecessary.
For that person, Linux is the right answer. The laptop will run twice as fast. The browser will be the same browser. The video calls will work. The grandkids will look exactly the same.
The bad days are the days when something printer-related goes weird, or a brand-new website doesn't quite display right, or they want to use a piece of software that turns out not to have a Linux version. Those days happen. They're not catastrophes (there's usually a workaround). But they're real.
The right Linux user is someone who can tolerate the occasional small friction in exchange for a free, fast, reliable computer.
Which version (and the fact that there are versions)
This is where Linux gets confusing if you read the internet, because there are hundreds of versions. Most of them don't matter for you. Three do.
Linux Mint. Great for first-time Linux users coming from Windows. The interface feels familiar: a task bar at the bottom, a menu in the corner, windows that close with an X in the top right. Boring in the best possible way.
Zorin OS. Specifically designed to look and feel like Windows. Pretty. Polished. Has a paid version that adds extra software, but the free version is fine. A very nice option. The new version has extra features to help the transition from Windows.
elementary OS. Looks more like a Mac. Worth knowing about if your old PC owner used to use a Mac and would prefer that aesthetic.
You don't need to research distros. You don't need to learn what a distro is. Pick one, install it, get on with your life.
What the actual experience looks like
Day one feels different. The wallpaper is different, the icons are different, the file manager is different. You will reach for something familiar and not find it.
Day three feels mostly fine. You've found the browser, you've gotten email working, the printer is set up, video calls are working.
Day fourteen, you mostly forget you're using Linux at all. The browser is the browser. The mouse moves. Things print. Calls happen.
The exceptions are usually:
- That one printer with a finicky driver (usually solvable but sometimes not)
- That one piece of software you didn't realize you used until you tried to open it
- That one website that doesn't work quite right in any browser other than the one you used to use
Those exceptions are the reason this option is right for some people, not most people.
This is something I do
A Linux install for a non-tech user is a different thing than what you'd find on a Linux forum. The forum advice assumes you want to tinker. You don't. You want a working computer.
What I do:
- Confirm the old PC is actually a good candidate (some are; some really aren't)
- Install the right version of Linux for what you'll actually use it for
- Set it up to look as familiar as possible
- Migrate over your important files, bookmarks, and email
- Configure the printer
- Walk you through the handful of things that are different
- Leave you with a written cheat sheet for the first two weeks
The cost is generally less than a single new monitor at Best Buy. And the computer comes back working faster than it did when it was new.
This is the frugal path. It's also a way to keep a perfectly good machine out of the landfill, which I appreciate on principle.

That wraps the week
Five days, four paths:
- Enroll in ESU and stay on Windows 10 a bit longer
- Buy refurbished Windows 11 (the sweet spot for most people)
- Switch to a Mac (right for fewer people than think they want one)
- Put Linux on the old PC (right for fewer people, but the cheapest option by far)
This afternoon I'm sending out the newsletter with a one-page decision guide that walks you through which of these four is yours. If you're not subscribed yet, this is a great time to start.

That Old PC in the Closet Has One More Career
The cheapest computer in 2026 is the one you already own. Linux can give a 10-year-old PC three more years of comfortable use, for the right kind of user. Here's the honest take.
