Common Questions

Is the 15-inch M3 Air worth buying in 2026?

Yes — it's the only way to get a big-screen Mac laptop without the price (or fan noise) of a 16-inch Pro. The M3 is quick, the 15.3-inch Liquid Retina display is superb for split-screen work, and it runs the latest macOS 26 Tahoe.
Should I choose 8GB, 16GB or 24GB?

8GB covers browsing, Office and student work comfortably. 16GB is the pick for heavy multitasking, big Photoshop files, Docker or local AI models. 24GB is for keeping serious workloads open all at once.
What's the difference between Fair, Good and Excellent?

Purely cosmetic — every Mac is fully tested and works perfectly regardless of grade. Fair has noticeable scratches or light dents (our best value), Good shows light signs of use, and Excellent looks like new. See our grading guide with photos.
Can it drive external monitors?

Yes — the M3 Air supports up to two external displays (with the lid closed), a step up from the single display of the M1/M2 Airs. Great for a docked desk setup.
What's included, and what about warranty and delivery?

Every Mac comes with a fully compatible charger, a 12-month RTB hardware warranty, 14-day returns, an 85%+ battery-health guarantee (under 400 charge cycles) and free insured next-day UK delivery on weekdays.
15-inch vs 13-inch Air — which should I pick?

Pick the 15-inch if the laptop mostly lives on a desk or lap and screen space matters — it's still only 1.51kg. Pick a 13.6” M2 or 13” M1 if it travels in a bag every day.
