I use the old chrome book I have for writing. It was pretty easy to throw Linux on there. Was cheap when I bought it years ago, and still has like 10 hours of battery life. Just don't expect it to do much other than text processing and simple Web stuff.
If I remember correctly, they're all core-boot-able, which is neat. Can't do that with most other laptops.
Like, I see the problem, but my school actually gave out iPads, which I feel was worse. On the chrome book, you can at least access the file system and Linux.
