That's what I did - emailed all the keys to myself via gmail and archived 'em. I originally signed up in anticipation of the Windows 7 launch, and I lucked into getting Office 2010 as well within the same 1-year period. I can't really think of anything else I'd want or need within the next year, and it's not like I can't just sign up again any time if something does come along.
True. I think the keys are the same for every version now too, IE 5 TOTAL Windows 7 keys, I thought it used to be like 10 keys for Ultimate, 10 keys for Home Pro, etc.
Good idea about gmail, archive 'em. That way I don't lose them. I had to install Office 2007 for school, but I'll want to get 2010 once I'm done with this BS core course.
