I bought this Chromebook 1 month ago and the touchpad broke, no "click" or "tap" registered.  Getting it fixed under Samsung warranty is very frustrating and wastes a lot of time.  They are very inefficient in the trouble shooting processes required to get a warranty claim approved.  After going through it on line in a live chat you'd think they would just send you a claim and tell you where to ship it to get fixed.  No, they send you to a web site to make the claim that requires you to put all the information about the problem in again.  Then they are supposed to call you to confirm the claim.  If you miss that call, they send you an email telling you to do the claim process again!I got it back, the touchpad is fixed but the return key doesn't work.  :(
