What reviewers say

Acer Swift Air 14

Reception for the Swift Air 14 line is generally positive, with owners treating it as a light, long-lasting machine for everyday work rather than a performance laptop. The 120 Hz screen and low weight draw the most praise, while the fixed 8 GB of memory is the usual complaint.

Pros

  • Smooth 120 Hz display
  • Long battery life in light use
  • Good value at entry-level prices
Cons
  • 8 GB RAM limits heavy multitasking
  • Modest processor performance under sustained load
  • Limited port selection on such a thin chassis

Lenovo IdeaPad Slim 3x 15.3" Laptop

The 4.5-out-of-5 average across 401 ratings points to satisfied owners overall, mostly around battery life and everyday speed. Complaints tend to center on Arm compatibility and the fixed memory.

Pros
  • Long battery life away from the charger
  • Smooth performance for office and browser work
  • Light build for a 15-inch machine
  • Quiet, cool running in normal use
Cons

Questions and answers

Which is better for travel and commuting?
The Acer Swift Air 14. At 1.19 kg and 12.9 mm it is far easier to carry than the 3.52 lb Lenovo, and its rated 19-hour battery lasts longer.
Which has more memory?
The Lenovo IdeaPad Slim 3x, with 16 GB versus 8 GB in the Acer. The Acer's RAM is soldered, so it cannot be upgraded later.
Is the Lenovo worth the extra $59?
Yes if you need 16 GB of RAM and a bigger screen for home office work. No if portability and screen quality matter more, since the Acer wins both.
Which screen is better?
The Acer's. It is 1920 x 1200 on a 16:10 panel at 120 Hz, versus 1920 x 1080 at 16:9 on the Lenovo. The Lenovo is larger at 15.3 inches.
Will all my Windows software run on the Lenovo?
Most will, but the Snapdragon X is an Arm chip, so some apps run through emulation and a few do not work. The Acer's Intel chip runs standard x86 Windows software natively.
Which lasts longer on a charge?
The Acer, rated at 19 hours of video playback from a 70Wh battery. The Lenovo is rated at 14 hours but supports Rapid Charge.
