Purchased this when it went on sale.  8 Gig, 256SSD model.  I have only experienced a few glitches.  Usually software not fully compatible with the new chip.  Cannot blame the device for that.Wish it had more ports... but, in many ways this is a blessing.  Forcing me to find clever solutions for the lack of plug in options.All in all, a good buy if you don't mind the Apple tax.
