Yes, I used a touch cover, I do not have a type cover. It may have been multiple things, a defective surface, a bad cover,... impossible to tell, I doubt is a generalized type cover issue as I would assume people would be reporting it all over the place.
I am a really happy camper, today I tested the RDP connection to my main server and works really well, you can get real stuff done using remote desktop. I was sure I would need the Surface Pro and now I am not so sure as I can do heavy lifting with more battery life and lighter device (and I will always need a "real" computer in the home anyway). Surface Pro looks awesome for pen and I am a big fan of ink well done (need to test a capacitive pen with the RT but usually they do not meet my bar). In any case, I will surely keep my unit, I did not feel so happy with a new gadget since the ZX spectrum, my first HP48 (yes, I am that old) or the iphone. I was not sure after reading some of the early reviews but this device is a geek's playground, I will be discovering new tricks for a while, the connection to the XBOX is pretty cool too and seems to work fine for movie navigation but did not play much with it yet.
