I really have to applaud Microsoft for introducing a "home" license for their software now. It's $130 here in the States on Amazon and you can install it on up to 3 Macs in your household. This is a great deal, and for the first time, MS Office is really affordable for the home user (that is not a student or teacher) that uses Word and Excel just a few time a month. Although I love OpenOffice, I think I will actually buy MS Office for my 2 Macs.
I really hope that Microsoft is setting a precedence here and that other big companies like Adobe will follow their example. I always wanted Photoshop for the Mac, and if it were available for $130 as a home license you can install on multiple Macs, I would totally buy it.
