Not sure why anyone is surprised at this.  Companies I contract for will not subsidize products unrelated to their core business, and I am a MCSE/MCSA.  Do you think for a moment Apple is buying their developers that develop OS X software Windows PC's?  They aren't.
I wanted a Mac Air, I bought it on my dime.  Walked out the door of Best Buy with it and a copy of Windows 7 knowing full well I couldn't bill the company for a non native Windows machine.  Best Windows laptop I've ever owned, btw.  I got an iPhone on my dime, knowing said employer will only support write-offs/subsidy of Blackberry products.
