Chromebooks are now the most popular school laptops of them all. If your school doesn't supply them, here are your best choices.
You can use the great Asus Chromebook Flip as both a laptop and a tablet. It's also the first Chromebook that fully supports Android. With a quad-core 1.8GHz ARM processor, 4GBs of RAM, and 16GBs of flash storage, it has just enough of what you need to be an excellent small -- 10.1-inch display -- Chromebook for school. It retails for $260.
If you want to take the Richie Rich approach to school, buy the top of the line and the most expensive Chromebook of them all: The 2015 Chromebook Pixel. You won't need it for K-12, but it's great for your MBA. The lowest-end model has an Intel Core 2.2Ghz i7 CPU, 16GBs of RAM, a 64GB SSD, 802-11ac Wi-Fi, and the best screen -- 1,560-by-1,700-pixel resolution, with 3:2 aspect ratio -- I've ever seen on any laptop. It will cost you though: $1.299.
You probably never heard of this company or this Chromebook. Schools have though. As Pascal Vallet, Director of Academic Technology at the United Nations International School, explained, "Our favorite (and students favorite) was the CTL NL6 as it is robust and has a handle to carry it." This sturdy Chromebook can handle the rough and tumble of kids. It's powered by a 2.4GHz Intel Celeron N3160 CPU, 4 GBs of RAM, 32GBs of SSD storage, and a good 11.6" display. This education specific Chromebook currently costs $239.
Can't spring for a Pixel but you still want a great screen? In that case, you want the latest HP Chromebook 13. While it's also no Pixel for speed, with its Core M5 processor, it's faster than any other Chromebook out there. It also has 32GBs of internal storage, and up to 16GB of memory. At $595, it's not cheap, but it's also a nice mid-range Chromebook between the luxury of a Pixel and the $200 models.
