What reviewers say

ASUS Chromebook CX15

  • 4.3 / 51,816 ratings

With 4.3 out of 5 from 1,816 ratings, owners mostly treat the CX15 as a solid budget Chromebook for browsing, schoolwork and streaming. Complaints center on slow performance under load and the plain build.

Pros
  • Big, bright Full HD screen for the money

  • Sturdy feel and a useful port selection
Cons
  • Sluggish with many tabs or heavy web apps
  • Plastic chassis feels basic

Lenovo IdeaPad Slim 3 15" Ryzen 5

Owners of the IdeaPad Slim 3 line generally call it solid value for light work, with a comfortable keyboard and a screen that is easy on the eyes. Complaints center on the 8 GB memory ceiling, the small 256 GB drive and a plasticky build.

What people mention
  • MemoryCriticisedOwners say 8 GB of RAM is the main bottleneck and is often soldered, so it cannot be upgraded.
  • StorageCriticisedThe 256 GB SSD is called too small once Windows and a few apps are installed.
  • BuildCriticisedReviewers describe the plastic body as flexible and basic compared with metal laptops.
  • PerformancePraisedThe Ryzen 5 7530U is seen as quick enough for browsing, office work and streaming.

Questions and answers

Which is better for schoolwork?
For browser-based schoolwork and Google Classroom, the ASUS is enough and much cheaper. If your school requires Windows-only software, get the Lenovo.
Which lasts longer on a charge?
The ASUS claims up to 13 hours. Lenovo does not publish a figure for this model, and Windows laptops in this class usually run shorter than a Chromebook.
Is the Lenovo worth the extra $183?
Yes if you need Windows apps, 8GB of RAM, or a 6-core CPU. No if you only browse, stream, and use Google Workspace.
Can the ASUS run Microsoft Office?
It runs the web and Android versions of Office through ChromeOS. The full desktop Office suite needs Windows, so choose the Lenovo for that.
Which is better for travel?
They weigh about the same, around 3.6 lb. The ASUS wins on battery life and the MIL-STD durability rating.
Does the Lenovo have a touchscreen?
The listed specs do not include a touchscreen. The ASUS listing does not either.
