Had mine a month. The only thing I noticed at first was it was losing the type cover when it went to sleep. This only happened if I popped it off when it was asleep then tried to wake it without it. That problem seems to be solved (with an update?) now as it just always works??? Other than that, zero problems and I use it pretty hard. I also tinker with a lot of software and have had no problems really with anything including apps. Truecrypt works just fine for anyone interested.
And btw, I have both office 2010 and 2013 installed, all of my other software, pics, vids, music, etc. and still have half of my hard drive (128g) left. I also plugged in a 64g micro sd card just because (just venting about all the hd size hype).
Anyway, nice machine, I wouldn't trade it for anything else out there. Oh, and I bought a RT charger and it works just fine on the pro. Reserving that for trips. So what's left? Not much, there will be updates as we go and it will just get better.
