As some may know, my SP3 started freezing and then would be alright after booting back up (up to this point, I'd had no issues with it). Finally, though, it wouldn't boot to Windows. Went online to MS support and asked that they call me about my SP3. They did (several times before I was done) and they went through trying to get it to boot. They finally had me download a recovery image from them and try booting with the image on a USB drive. It booted up into the recovery image), but it couldn't repair, refresh or reset. It looked like the SSD had failed somehow. Arranged an exchange - this was Monday later in the day that I was dealing with MS support. I received my brand new SP3 i5 256 by FedEx on Wednesday! That may be the norm with MS support, but, man, I have to give them credit where credit is due. They handled this well!
