Price/spec verdict

What you get for the money

Strong if the checkout reduction appears: £1,129.99 would be a good UK price for a new 15-inch MacBook Air M4 with 16GB RAM and 1TB SSD, but the visible Costco product page was £1,399.99 when checked.

Terms that affect the real price

  • Do not rely on the £1,129.99 figure until the Costco basket or checkout shows it; the visible product page price was £1,399.99 during this check.
  • Costco membership is required, and local warehouse prices can vary from the online page.
  • The MacBook Air has a 60Hz display and fanless design, so heavy sustained creative workloads still suit a MacBook Pro better.

Why it works

Reasons it is worth a look

  • At this price, this is still a strong price/spec mix for a new 15-inch MacBook Air M4 with 16GB memory and the roomier 1TB SSD.
  • The 15.3-inch Liquid Retina display, fanless design and roughly 1.51kg chassis suit students, office work, travel and everyday creative tasks better than many Windows ultrabooks at similar money.
  • Costco is a credible UK retailer, and the matching 15-inch 16GB/1TB configuration loaded with an in-stock signal.
