Plain-English buying guides for every category we compare — what each spec really means, how much it moves our 0–100 score, and what's normal right now, with figures computed live from our catalogue.
Buy the phone whose strengths match how you actually use it. A good screen and all-day battery matter to almost everyone; cameras and raw power only if you really lean on them. Set your budget first, then let the one or two specs you care about break the tie — don't pay for the rest.
Start with what you'll actually do. For browsing, office work and video, almost any current laptop with 16GB of RAM is plenty — spend your budget on a better screen, a comfortable keyboard and a lighter build. Only pay up for a 'Pro' processor or dedicated graphics if you game or edit heavy media.
Decide how you'll wear them first: over-ears for comfort and sound at home or on planes, earbuds for the gym and pockets. Then pay for the two things you'll actually notice every day — good active noise cancelling and all-day battery — and don't get talked into codecs or driver sizes that won't change what you hear.
Match the panel to the job: fast high-refresh for gaming, colour-accurate IPS or OLED for creative work, a big sharp panel for the office. Size and resolution set the whole experience, so get those right first, then let refresh rate, HDR and ergonomics break the tie. Don't pay for 4K on a small screen or 240Hz you'll never push.
Start with the room and the use. For a dark room and movies, OLED's perfect blacks are hard to beat; for a bright room or sports, a high-brightness Mini-LED wins. Gamers should insist on HDMI 2.1 with 120Hz and VRR. Get size and panel right first — the smart platform and speakers matter far less and can be fixed cheaply later.
Buy into a system, not just a body — the lenses you'll add matter more than any spec. Pick a sensor size that fits your budget and how much you'll carry, then let autofocus and (if you shoot video) the video features break the tie. Megapixels are near the bottom of the list; almost every current camera has more than enough.
Decide what it's for first. For couch browsing and video, a mid-range tablet with a good screen is plenty; for drawing or note-taking, prioritise stylus support and display quality; to replace a laptop, pay for the chip, RAM and a proper keyboard. Buy enough storage up front — most tablets can't be upgraded — and don't overpay for power you won't use.
Check compatibility first — the best smartwatch is one that fully works with your phone. Then decide between all-day smart features (and nightly charging) or multi-day battery for sleep tracking and workouts. Pay for the health sensors you'll actually use, and don't buy features tied to an ecosystem you're not in.
Decide between a locked-down, easy console-like device and an open Windows handheld you can tweak. Then weigh the three things you'll feel every session: screen quality, real battery life and how it sits in your hands. Raw power is tempting, but a comfortable, efficient handheld you actually pick up beats a powerful one that cooks your palms and dies in an hour.
Pick the ecosystem you'll buy books from first, then the screen size for how you read. Most people want a 6–7 inch waterproof reader with an adjustable warm front light — that covers bedtime and bath reading beautifully. Only pay extra for colour or note-taking if you specifically need them; for plain reading, a great black-and-white screen still wins.
Match the chip to the workload and the rest of the build. Gamers should spend on strong single-core speed and pair with a good GPU rather than chasing core counts; creators and compilers benefit from more cores and threads. Check the socket and cooling before you buy, and don't pay for an overclockable, high-wattage chip you won't push.
Buy the GPU for your target resolution and refresh rate, and make sure it has enough VRAM to last. Check it fits your case and your power supply can feed it before you commit. Chase real-world benchmarks at your resolution rather than headline specs, and weigh upscaling and ray-tracing support if those features matter to you.
