My experience is that the touchpad on Chromebooks is high quality and really nice (I prefer it to a lot of other touchpads I've worked with). I can also boot fully into Linux (slightly different than what is described in the tweets), however when using Linux, the touchpad becomes terrible.

I'm guessing if I spent time figuring out the proper drivers I could probably get it working nice on Linux too but it just hasn't been worth the effort for me.

I really like the keyboard too, but I think that is probably more individual taste.
