I got that email too.
ad I'm like many here, all machines other than my mac, are running XP. I used Vista briefly, but didn't like it at all. Like Micah, I will wait until I need to buy a new PC to try windows 7. But m Windows boxes are all no more than 2-3 years old, and my next replacement will be the iMac in about two years.
BTW, have you guys seen how cheap you can get an iMac these days?!
