Yeah me too... until today that is. Just picked up iLife '08
and didn't realize I picked up the Family Pack copy. Needless to say, I was in a rush, so didn't think to check before paying. Since I intend on installing this on my 3 Macs, I guess I'll consider the extra $20 a payback for all the shareware I've used but never bought... is Office shareware??? 
In reflection, I guess it is the honest thing and since so many have made a statement that using the single user on multiple Macs - although owned by oneself is still considered stealing. The extra $20 is worth the piece of mind knowing that you are supporting the best computer company and I appreciate it because it's made my time wasting more worthwhile. Thank you Apple!
