I got a Toshiba Chromebook 2 (4 GB RAM, 32 GB storage, decent screen, but an anemic processor), thinking it could replace an old MacBook we use for web, email, and music. The email didn't work so well, because we couldn't easily see multiple accounts at once. I put in an SD card full of music, but the players I tried were all terrible.
I can see wanting 8 GB of RAM, but I'd need Crouton to make use of 16 GB.
Wish Google would adopt that attitude for their Nexus line as well...
