Which computer should you buy? What actually matters in 2026

For ordinary use, meaning the web, email, photos, video calls and a bit of paperwork, four things decide whether a computer stays pleasant for six years or becomes irritating in year two: enough memory, an SSD, a decent screen and reasonable battery life.

The processor, which the salesperson will happily discuss for ten minutes, comes a long way behind. It is the number most prominently advertised in shops and it is also the one that will change your day the least, because any processor sold new today is far more than enough to read your email.

Here is how to read a spec sheet without being told a story.

Memory: the one number not to get wrong

Memory, or RAM, is the computer’s working space. It decides how many tabs and applications can stay open before everything starts to crawl.

Today, 16 GB is the sensible floor. An 8 GB machine still works, but it is already cramped with a browser, a video call and a photo app open together, and that situation will not improve three years from now.

The expensive detail: on the large majority of recent laptops, every Mac included, the memory is soldered in and cannot be added later. The choice you make at the counter is permanent. If your budget has to give somewhere, let it give on the processor or the storage, never on the memory.

On a desktop, memory is usually still replaceable, which makes an 8 GB model far less of a gamble.

SSD or hard drive: the difference you feel daily

An SSD has no moving parts. It starts the computer in ten seconds, opens applications instantly, and makes no noise at all. A traditional spinning hard drive takes a minute and a half to boot and clatters every time you open a folder.

On laptops the SSD has become standard. What remains are entry-level desktops and tempting sale prices still fitted with a mechanical drive. Do not buy them. It is the one item on this list that can single-handedly make a brand-new machine unpleasant on day one.

For size: 512 GB is comfortable for most people. 256 GB is fine if your photos mostly live online and you install no large software. Below that you spend your life clearing space.

The processor: why the model numbers confuse you

Manufacturers publish names each year that resemble last year’s, with numbers that mean different things from one brand to the next. The result is an unreadable spec sheet, and that is somewhat the point.

Three markers are enough.

Generation matters more than tier. A recent mid-range processor often beats a five-year-old high-end one. Look at the model year first, then at the tier.

Mid-range is the balance point. From Intel, a Core i5 or its equivalent. From AMD, a Ryzen 5. From Apple, the base chip of the current generation. Going one step up sometimes doubles the price for a gain you will never notice while reading email.

Avoid the absolute entry level. The cheapest chips, usually found in the least expensive big-box laptops, are built to hit a price tag and struggle the moment you open several things at once.

The screen, the detail nobody checks in the shop

You will stare at it for hours a day, and it is still the specification people read last.

The reasonable minimum resolution is 1920 x 1080, often written “Full HD” or “FHD”. Cheap laptops still ship with less: the text on those is visibly soft, and it tires the eyes much faster.

Brightness matters at least as much. A dim screen is hard to read in a sunny living room. In the shop, put two machines side by side at the same brightness setting: the difference is obvious.

Matte or glossy. A glossy screen has more contrast but mirrors the windows behind you. A matte one is easier on the eyes in a bright room. It is a matter of taste, but make the choice deliberately.

And look at the size honestly. A 13-inch is light and travels anywhere; a 15 or 16-inch is far more comfortable if the computer lives on the kitchen table. Weight is the same kind of decision: a laptop that never leaves the house can afford to be heavy, and one that goes to the cottage every weekend should not be.

Battery life, and what really determines it

Advertised battery figures are measured under optimistic conditions. Take a third off for real use.

What genuinely helps: laptops built on ARM chips, which includes every recent Mac, often last a full day of light work. Many conventional Windows laptops land nearer six to eight real hours, which is still perfectly fine.

What ruins it: a very bright screen, a dedicated graphics card, and leaving the machine plugged in at 100% permanently. If you always work at the same desk, chase screen comfort instead; battery life is not your problem.

Mac or Windows, honestly

Both are excellent. The real deciding factor is not technical.

Buy a Mac if you already have an iPhone or an iPad, if you want a machine that ages well and stays quiet, and if the higher entry price is not an obstacle. The integration with the rest of Apple’s world is genuine: photos, messages and files follow you around by themselves. The downside: less flexibility, no way to add memory, and expensive repairs out of warranty.

Buy a Windows PC if you need a specific piece of software that exists only there, if you play games, if your budget is tight, or simply because you have known Windows for twenty years. The choice is enormous at every price, and a good PC around $900 exists, where a Mac at that price is an entry model.

The factor people underestimate is habit. Switching systems at seventy, after thirty years of Windows, costs more in frustration than any saving at the till. That is not a reason never to switch, but it is a reason to do it with help nearby.

If you are crossing over, our piece on moving to a new computer covers what transfers and what never does.

What not to pay for

A dedicated graphics card, if you do not play games or edit video. It adds to the price, runs hot and drains the battery for no benefit in ordinary use.

A 4K screen on a 13-inch laptop. The difference is invisible at that size and the battery pays for it.

A 144 Hz or faster display, unless you game.

The store’s extended warranty. Read what it actually covers before signing; it is frequently less than the manufacturer’s warranty and your credit card already provide.

The preinstalled paid antivirus, sold with a discount for the first year. Windows and macOS both ship with built-in protection that is enough for most people.

The in-store “setup service”. What they do in twenty minutes is what any first boot does by itself.

One thing worth spending on instead: the ports you will actually use. A machine with nothing but two USB-C sockets means an adapter for the printer, another for the old external drive, and a dongle living permanently in the bag. An HDMI port and a full-size USB port are worth more in daily life than a faster processor.

Refurbished, a genuine option

This is the best way to get more machine for less money, and it gets dismissed far too automatically.

Two good seams: manufacturer-refurbished stock, sold with a warranty, and former business laptops coming off lease. The latter were built to survive daily abuse, are easy to repair, and their price falls sharply after three years.

What to check before buying:

1. A written warranty, even a short one. Three months minimum, a year is better.
2. The battery’s condition, on a laptop. It is the part that wears out, and replacing it costs money.
3. That the machine supports the current version of Windows. A great price on a computer stuck on a version that is no longer supported is not a bargain, as our article on the end of Windows 10 support explains.
4. That memory and SSD meet the thresholds above, or that they can be replaced.

Where to start

Set your budget, then fill the boxes in this order: 16 GB of memory, an SSD of at least 256 GB, a Full HD screen, and only then the processor with whatever is left. You will end up with a better computer than the person who did it backwards for the same money.
