Buying a Laptop: What Matters and What Is Sold to You

Laptop specifications are written for people comparing numbers. The things that determine whether you enjoy using one for the next five years are mostly not numbers, and mostly not on the label.

Here is what to check, in order of how much it matters.

The four that matter most

1. The screen

You will look at it for hours, and it is the thing people regret most.

Check it in the shop, not on paper. Take something you would actually read and look at it.

Matte rather than glossy if you work near a window. Glossy screens are more vivid and reflect everything behind you.

Brightness matters more than resolution for readability. A bright modest screen beats a dim sharp one.

Bigger is better for reading, worse for carrying. A 15-inch screen is comfortable at a desk. A 13-inch is comfortable on a train. Decide which you actually do.

Ignore high resolution as a selling point unless you edit photographs. On a laptop screen the difference is marginal, and it costs battery.

2. The keyboard

The second thing you touch constantly and the second most common regret.

Type on it. A full paragraph, in the shop. Keyboards vary enormously and the difference is immediately obvious under your hands.

Check the key travel — how far keys move. Very shallow keyboards are unpleasant for long typing and some people cannot get used to them.

Check for a backlight if you use it in low light.

Check the layout. Some manufacturers move the arrow keys or shrink the right-hand shift key to fit a number pad. If you touch-type, this is maddening for months.

3. Weight

Pick it up. If it is going to move around the house or travel, half a kilo is the difference between carrying it and leaving it on the desk.

Include the charger. Some are substantial and you will carry both.

4. Battery life

Assume the advertised figure is optimistic — it is measured under gentle conditions. Real use is typically a good deal less.

Anything under about six real hours means you are tied to a socket, which removes much of the point of a laptop.

The specifications that actually matter

Three numbers, and the rest is noise for ordinary use.

Memory (RAM): 16 GB. The single most important specification for whether a machine still feels fast in four years. 8 GB is workable today and will not age well. On most modern laptops this cannot be upgraded later, so choose it at purchase.

Storage: 512 GB, and it must be an SSD. Every current laptop uses one; if you see a "hard drive" or "HDD" on a cheap machine, avoid it — it is the single biggest cause of a computer feeling slow.

Processor: any current mid-range one. For email, web, documents and photographs, the difference between mid-range and high-end is invisible. The money is better spent on memory and the screen.

Ignore the graphics card unless you play games or edit video.

What to check that nobody mentions

How many ports, and which. Some very thin laptops have two, and both may be needed for charging. If you use a printer, a memory card, a mouse or an external screen, count them.

Whether it has a headphone socket. Increasingly not guaranteed.

How the lid opens. Some require two hands. Trivial, and it will irritate you daily.

Where the vents are. Some blow warm air onto the hand using the mouse.

Fan noise. Ask the shop to open something demanding, and listen.

The webcam quality, if you make video calls. Frequently poor even on expensive machines.

Windows or Mac

Neither is better in general, and the honest guidance is narrower than either camp suggests.

Stay with what you know, unless there is a reason to change. Familiarity is worth more than any feature difference, and the cost of relearning is real.

If your phone is an iPhone, a Mac connects to it more smoothly — photographs, messages, files.

Windows costs less at every level and offers far more choice.

Chromebooks are inexpensive, simple, and secure, and they are genuinely good if everything you do is in a browser. They are poor if you need specific installed software.

Where to buy

In a shop, if you can. The four things that matter most are all things you have to touch.

Refurbished from a reputable seller with a warranty is frequently the best value available, particularly for business models built to last.

Last year's model is usually a substantial discount for differences you will not notice.

Check the warranty and what it covers. Extended warranties are heavily promoted because they are profitable; whether one is worth it depends on the price, which is worth working out rather than deciding at the counter.

Setting it up so it stays pleasant

Turn text size up before deciding the screen is too small. Windows and macOS both scale everything, and the default is set for younger eyes.

Remove the preinstalled software. New Windows laptops arrive with trial programs that slow the machine and nag. Uninstalling them takes twenty minutes and is worth doing on day one.

Turn on automatic updates.

Set up backup immediately, before the machine has anything on it worth losing.

The version worth remembering

16 GB of memory, an SSD, and a screen and keyboard you have physically tried.

Everything else on the specification sheet is a distant second, and the two things you cannot judge from a website are the two you will notice every day.
