iPad Mini for Chromebook?

[Wesley Files]

Well, I find the internet pretty distracting myself

If you're using Google Docs, that will work offline if you want to disconnect from the internet while writing. It sounds like a good option, and I think you'll be happy as long as you know that the "app store" for each device is quite different. iOS has a lot of games, and apps that are specialized versions of functions you'll find on websites. Chrome OS really doesn't have that many custom made games (though you can play with a whole internet's worth of Flash games) and you'll just use the real website instead of an app version.
