I'm a long-time Windows user who decided to make the switch to this Chromebook, and I must say, I've been very pleased.  Although it is ultimately a very different kind of computer, Samsung's Chromebook 2 is in a lot of ways surprisingly well thought out MacBook Air knockoff.  It's very light and thin, exceptionally easy to navigate, and quick.  Battery life is solid.  Although there may very well be a lot of things this Chromebook can't do, it does absolutely everything I need.  It's unlikely I'll be going back to Windows and I certainly won't be shelling out $900 a MacBook Air.  My only 'complaint' relates to the screen.  Although it's really quite crisp and bright, it could be better.
