I am currently on a Chromebook and this thing is amazing. I've had it for over six months and am pleased as punch, even alongside by beefy desktop computer and the sexy tablet. The Chromebook is excellent for web browsing, emails, Google Docs (and the like - SkyDrive if you're still somehow a Microsoft fan), et cetera. Plus it has a ridiculously long battery life, no fan noise, and weighs less than my previous Toshiba netbook. 8-second bootup, no viruses, no setup required, always updated. It's exactly what it should be.
I don't stream torrents, I don't use Linux, I don't need to do graphic design or run heavy-duty software or anything of the sort on this machine. I have other machines for that stuff. This machine is for reading BoingBoing in bed at night and posting long comments without wrestling with a damn tablet keyboard, and for that this thing gets an A+.
