Essential buying tips

• Get 16GB of RAM. It’s the single best upgrade for longevity.
• Insist on an SSD. Avoid any laptop still using a slow hard drive.
• Match the OS to your needs. A Chromebook is cheaper if you only browse.
• Don’t chase specs you won’t use. Most people don’t need a gaming GPU.
• Avoid suspiciously cheap listings advertising huge RAM and storage, they’re often reseller-modified.

The big tips: buy 16GB of RAM (see the IdeaPad Slim 5), don’t pay for an OS you won’t use (a Chromebook Plus 515 for light users), and weigh battery and build (the MacBook Air M4). Compare specs, not just prices, and you’ll buy once and buy well.

Frequently asked questions

What’s the most important thing when buying a laptop?

RAM and storage type matter most for everyday speed and longevity: aim for 16GB of RAM and an SSD. After that, match the operating system to your needs and prioritize battery life and a comfortable screen.

How do I avoid a bad laptop deal?

Be wary of unknown brands advertising huge RAM and storage at suspiciously low prices, they’re often reseller-modified units. Stick to reputable brands and current processors, and compare specs rather than just the headline price.

Is it worth paying more for an OLED screen?

If you stare at your screen for hours, yes, OLED is sharper and easier on the eyes, as on the Zenbook 14 OLED. For light, casual use, a good IPS screen is perfectly fine and saves money.
