My wife switched to a SP3 from a macbook, because it looked like a very compelling device.<p>It lost all bluetooth and wifi - 4 months out of warranty (hardware issue).  From googling - this was not a completely uncommon occurrence.<p>Yes - we should have gotten the extended warranty, but this was an expensive device, and we expected quality hardware that would last.<p>From a usability perspective, it is a device that is in-between. It is not a stellar tablet nor a stellar laptop.
