Well, I did it. Downloaded and installed the 64 bit version. For those of you who want to know how to install: Burn the ISO using Disc Utility Insert DVD and restart the computer Hold Option key and select the Windows CD from the boot menu It's easy. The only hurdle I have come across is sound drivers. I can not get any sound working. I have a Jan '08 8 Core Mac Pro. I think Microsoft are really onto something here. The new task bar is great. Any other issues or opinions users would like to share with the rest of the community?
