The software is amazing. On my 1.83 gHz iMac with 1 gb of ram, Win XP Pro performs almost as well as it does natively. I saw on the forums that sound and USB support will be included in the release version. The only wishes I have now are that the number keypad work and that keys repeat if you hold them down. If these features are already included, please let me know how to make them work. I'm making a pre-purchase right now ... Thanks!
