I can connect to my enterprise 802.1x network using both my Samsung Captivate and my Nook Color. The Nook easily connects when running CM7 and the unrooted factory software (version 1.3). I don't think it's the OS. I don't work in the IT office, but I know the people who do, and they had to do some things to get the wifi to work with Android. Sorry I don't know the details.
