Sorry, wasn't keeping an eye on replies - I just kind of threw my original comment out into the ether. I'd like to ask you though. What are the other 4 (5? 3? you said roughly) cash cows do you reckon, and in all seriousness are any of them even close in scale to Windows/Office? Honestly, I mean :)
