    What reviewers say

    Lenovo IdeaPad Slim 3x

    Rated 4.6 out of 5 from 76 ratings, owners generally like the screen, keyboard and price for a Copilot+ laptop. The recurring caveats are Arm app compatibility and the modest SSD.

    Pros
    • Good value for a Copilot+ PC
    • Bright, matte 16:10 display
    • Comfortable backlit keyboard
    • Light metal build for a 15-inch
    Cons
    • Some apps need emulation on Arm
    • Storage fills up quickly
    • Battery life falls short of the marketing claim for some users

    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
    • Low weight and slim build for daily carrying
    • 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

    Questions and answers

    Which is better for students?
    The Acer Swift Air 14 suits students who carry a laptop all day, because it weighs 1.19 kg and lasts up to 19 hours on video. Pick the Lenovo if you run many apps at once, since 8 GB of RAM fills up fast.
    Is 8 GB of RAM enough on the Acer?
    For browsing, email, and documents, yes. For many tabs, large spreadsheets, or video editing, no. The memory is soldered, so you cannot add more later.
    Which lasts longer on a charge?
    The Acer. Its 70Wh battery is rated for 19 hours of video playback. The Lenovo has a 60Wh battery, and its listing states only 2 hours.
    Is the Lenovo worth $120 more?
    Yes if you need 16 GB of RAM and a 15.3-inch screen, since neither can be upgraded later. If you mostly browse and write, the Acer saves you $120.
    Can I upgrade the storage on either?
    The Lenovo has a free M.2 slot for a second SSD. The Acer lists a 512 GB SSD but no spare slot, so plan on external storage.
    Will my Windows software run on the Lenovo?
    Most apps do, but the Snapdragon X chip runs Arm64 Windows. Some x64 apps and drivers need emulation or do not work. Check your key software before buying.
