I really like this Chromebook. I've moved all my most common tasks to the cloud (Google Drive w/Docs, LucidChart, etc) and there isn't much I can't do on it. Development and heavy-duty movie/photo processing is still on a "real" computer, but even development can be done in the cloud now (Codenvy), it's crazy.
And while I know my Chromebook is slower than my MacBook, it doesn't feel slower. It actually feels faster - it only does one thing, and the entire system is tuned to that task, making it feel very snappy. Yes, I said "snappy" - deal with it.
My only gripes:
- All ports (except headphone) are on the back. That can be a little annoying, although that's where most cables naturally want to be so it's only a minor peeve.
- The unit closes really tightly - it's definitely a two-handed operation to open it up because it is so light!
- No Cisco IPSEC support, which is what my work VPN requires.
- Memory not expandable - comes with 2 GB which works quite well, but I'm sure 4 would be better!
Overall, I am really in love with the Samsung Series 3 Chromebook - highly recommended!
