Phones, computers, audio and connected devices: understand model differences and decide which specifications matter for your purchase.
Start with the job you need a device to do: working away from a desk, taking photos, gaming and keeping a computer for years call for different priorities. A faster processor or larger screen cannot make up for poor battery life, incompatible connections or software that does not support your workflow.
These guides connect specifications with practical uses. Check the exact model variant, included accessories and manufacturer support before choosing. Catalogue offers help you compare current prices; editorial guides explain which differences deserve your attention.
Start with these guides
What to check before buying
| Criterion | What to check | Why it matters |
|---|---|---|
| Main use | Match performance, screen and battery to your everyday tasks. | Avoid paying for features you rarely use. |
| Compatibility | Check connections, operating system, apps and existing accessories. | Adapters and licences can change the total cost. |
| Useful life | Check updates, repair options and battery replacement for the exact model. | Ownership costs extend beyond the initial purchase. |
Mistakes to avoid
- Treating different storage variants as the same product.
- Assuming laboratory battery figures apply to every workload.
