.... That Apple's resurgence has bit Microsoft in the butt big time is probably bittersweet to those who made the decision for what were at the time sound business tactical reasons).
I agree with the rest of your comments, but I don't agree with this one. Well I didn't agree until last year.
The thinking goes that if someone buys a Mac it's a lost MS Windows sale. But many people (some think it's more than half) end up buying a Windows license for bootcamp or a VM. However, the Windows license bought for a Mac is probably going to be a retail license, not an OEM license.
The retail license presumably has a much larger profit margin than the OEM licenses that MS sells to people like Dell and HP. I would argue that while MS may be selling fewer Windows licenses to Mac owners, they are making more money overall because a retail license costs much more than the OEMs are paying.
Same thing for Office. Whether a Mac owner is buying a Windows version for their Windows VM, or buying the Office for Mac version... they are still buying a license from MS....and again, probably retail and not the OEM license.
I think that is why MS has been happy to keep developing Office for Mac - it helps to drive sales of Macs in general, who then buy the full-price versions of Windows and Office.
It's the PC makers themselves who get stung by Mac sales.
Of course that was only true until the last year or so..... because iPads don't do anything for MS - and therefore MS is now in the same boat as PC makers. I think we will see a huge push from MS to get their tablets into market because to not do so will actually see Apple eating MS's lunch.
imho, of course
