Well if you are a PC Win7 has come out this week, I know that several people here have been using the beta version for quite awhile. I have a dual boot system Vista Home and XP Pro using the latter when I am using the DAW. Just a little sceptical of upgrading the recording OS because everything is working great, not sure if there is really an advantage to changing anything. I am certain that dumping Vista on the other side is probably a good thing but is that going to create any conflicts with the dual boot set up? Love to hear from some people who have or are making the switch.
