Traded in my original RT for a 4/128 last week while at Ignite. Didn't read about the no go for Win10 Preview and put it on there, now having a hell of a time putting 8.1 back on it. On FAT32 formatted usb stick #2 with the image from MS website. Gets as far as 86% then gives up the ghost and says reset failed. Other than that so far so good, actually responsive, plus real keys are nice vs.the touch cover I had before. It would be nice to have the hinge from the SP3 on here instead of the 3 position, not sure how much more that would have added to the price point but it's missed.
