I got one of the small 11.6" screen refurbs off of Amazon, got a smoking deal on it. I use it solely for a "fiddle around on the web" laptop while my wife or kids are watching shows I don't really care about but I don't have something better to go do at that moment (aka, my "I should probably be dry firing or working out instead" laptop ).
For web surfing it's great. Basically anything you would normally do through your browser, it works very well. I vastly prefer it to the iPad for browsing forums and such. Battery life is very good.
Hardware wise, it does feel lighter and flimsier than a "real" laptop. I don't think it would take much physical abuse.
