Lenovo IdeaPad Slim 3i 15.6" Laptop vs ASUS Chromebook Plus CX34

The IdeaPad Slim 3i is the better pick for anyone who needs full Windows software, a number pad and a bigger 15.6-inch screen for office work or study. The ASUS Chromebook Plus CX34 is the better pick for a lighter, touchscreen machine with a stronger processor and a longer-rated battery, as long as you can live inside Chrome OS. Build quality is comparable at this tier, and both hold a 4.3 rating, though the IdeaPad has far more owner feedback behind its score.

  • Choose the IdeaPad Slim 3i if you need Windows apps, a numeric keypad and a larger screen for spreadsheets, schoolwork or office tasks.
  • Choose the ASUS Chromebook Plus CX34 if you want a lighter touchscreen laptop with a faster Core i3 and long battery life for web-based work.

Questions and answers

Which is better for schoolwork?
For essays, research and web-based classwork, the Chromebook Plus is lighter and faster. If your courses require Windows-only software such as certain statistics or engineering programs, get the IdeaPad.
Which has the better processor?
The ASUS. Its Core i3-1315U has performance cores and outpaces the IdeaPad's N305, which is an efficiency chip meant for basic browsing and documents.
Which lasts longer on a charge?
ASUS rates the Chromebook Plus at 10 hours. Lenovo gives no hour rating for the IdeaPad's 47 Wh battery, so real-world runtime depends on screen brightness and workload.
Can I run Microsoft Office on both?
The IdeaPad runs the full desktop Office suite on Windows. The Chromebook uses the web versions of Office or Android apps, which cover most basics but lack some desktop features.
Is the touchscreen worth stepping up to?
Only if you want touch input or tablet-style use with the lay-flat hinge. The IdeaPad's non-touch matte screen is fine for typing work and shows fewer fingerprints.
Which is easier to carry around?
The ASUS. It weighs about 3.2 lb in a 14-inch chassis, while the IdeaPad is 1.55 kg in a larger 15.6-inch body.
