Is the M4 MacBook Air 15-inch worth it over the 13-inch?

If you want more screen for spreadsheets, editing or split-screen work, the 15-inch is worth the extra size and weight. The 13-inch is the better pick if portability matters more than screen space.

How does the M4 Air compare with the M3 Air?

The M4 brings a faster chip and, on this configuration, 24GB of memory and a 2TB SSD. The chassis, 15-inch display, ports and battery rating carry over, so M3 owners have little reason to upgrade.

Is 24GB of memory and 2TB of storage enough?

For most buyers, yes. 24GB covers heavy browser use, large photo libraries and light video editing, and 2TB holds a big local file collection. Neither can be upgraded later, so buy the capacity you expect to need in three to four years.

How long does the battery last?

Apple rates it at up to 18 hours of video streaming from a 66.5-watt-hour battery. Real mixed use, with a bright screen and many apps, typically lands well short of that but still covers a full workday.

The laptop, a USB-C to MagSafe 3 charging cable and a USB-C power adapter. The adapter wattage depends on the configuration Apple ships.

The only price on record is $1,799 as of October 30, 2026. Apple laptops usually see discounts during back-to-school and Black Friday periods, so watch those windows.
