So...it's a nice device. Slim, lightweight, doesn't get hot like the SP3, doesn't seem to be affected by the WiFi issues that plagued the SP3 either. That being said -- the device feels a little more sluggish than even my SP2 with Core i5 CPU. Things like updating Windows or installing apps are pretty sluggish and apps take a little longer to load. Not sure what to think overall at this point... What does everyone else think?
