i have had no BSODs either. Only issue i had was Windows Media Player showed me black images with audio when pausing/playing a DVD, hasnt happened again though. Also it keeps wanting to install an Acer driver for my monitor but it always fails, did the same thing in vista though, and updating my ATI 2600 PRO driver does wierd shit so i can only go up to 1600x1200 not 1920x1200.
I even copied my Zune database info from my Vista partition and it works flawless.
Another issue is Netflix wont play shit in it.
This is Windows 7 64bit. So far it isnt any worse than Vista though. I like it. Networking works alot better, i dont know how long it took for me to get two Vista machines (one 32bit and one 64bit) and an XP machine to see eachother. This OS can see and access everything and i havent messed with any settings, even still got an automatic IP.
