How to pick a computer: a plain-English buying guide

Laptop or desktop, Windows, Mac or Chromebook, and the few specs that matter. No prices, no brand pitch.

The short version

Start with what you’ll actually do on it (email, video calls, photos, schoolwork, games), then pick the system you’re comfortable with (Windows, Mac or Chromebook), and check memory, storage and how long it will get security updates. For everyday use, you don’t need the most powerful model.

📅 Checked as of October 2026. We don’t list prices or pick brands; we have no sponsors. Apps and rules change, so check the sources below if something looks different.

1. Laptop, desktop or tablet?

  • Laptop: everything in one folding case; use it on the couch, take it on trips. Most people choose one.
  • Desktop (a tower plus monitor, or an all-in-one): a bigger screen and keyboard for the price, easy on the eyes and hands, stays at a desk.
  • Tablet (iPad, Android tablet): great for reading, video calls and photos. With a keyboard case it can handle email and light typing.
Think of it like this: picking a computer is like picking a kitchen: first decide what you cook most, then buy the counter space for it, not the restaurant kitchen.

2. Windows, Mac or Chromebook?

All three handle email, web browsing, video calls and photos well. The short version (more in Windows vs. Mac, explained):

  • Windows (many makers): the widest choice of models and sizes, and the most programs, including many work and school apps.
  • Mac (Apple only): works smoothly with iPhone and iPad, consistent menus, fewer models to choose from.
  • Chromebook (many makers, Google’s ChromeOS): simple, starts fast and updates itself; works mostly in the Chrome browser and with web apps, which suits email, browsing and Google Docs.

Sticking with what you or your family already know saves relearning, and makes it easier to get help.

3. The few specs that matter

  • Memory (RAM): lets you keep several apps and browser tabs open. More is smoother, especially for video calls with many tabs open.
  • Storage: space for files, photos and apps. An SSD is much faster than an older spinning hard drive. If you keep lots of photos, get more storage or use a cloud service (see the cloud, explained).
  • Screen and keyboard: try them in a store if you can. A larger, brighter screen and a comfortable keyboard matter more day to day than raw speed.
  • Battery (laptops): check independent reviews for real-world battery life.
  • Ports: make sure it has the plugs you need (USB-C, USB-A, HDMI for a TV or monitor), or plan on an adapter.

4. Updates: check how long it will be supported

Security updates keep a computer safe for banking and email. Before buying, especially a used or older model:

  • Windows: Microsoft ended support for Windows 10 on October 14, 2025. A new computer should come with Windows 11. If you keep a Windows 10 PC, Microsoft offers Extended Security Updates for home users through October 12, 2027.
  • Chromebook: Google says Chromebooks get 10 years of automatic updates from the model’s platform release. You can check the end date in Settings → About ChromeOS → Additional details.
  • Mac: Apple doesn’t publish a fixed number of years, but Macs have typically received updates for many years. Check that the model runs the current version of macOS.

5. New, refurbished or used?

A refurbished computer from the maker or a reputable seller, with a warranty and a clear return policy, can be good value. Check how many update years are left, and be wary of very old models sold cheaply.

6. Moving to the new computer

Back up the old one first (see the 3-2-1 backup rule). Signing in with the same account (Microsoft, Apple or Google) brings back many settings; a cloud service or an external drive moves the rest. Set up a password manager so your logins come with you. Before giving away or selling the old computer, sign out of your accounts and reset it.

Quick tips

  • Write down what you’ll use it for, then shop for that.
  • Check how many years of security updates it will get.
  • Keep the old computer until everything has moved over.
