Well, given the cost of off time in a $billions factory, I really don't
think that IBM will play that game just to "buy" a good new image to their
piece of software. The point is undoubtly reliability.
About the same point a friend of mine that is currently administrating a
2000+ machines parc tells me that windows servers *have* to be restarted at
least once a week. Unix/linux ones they have are *never* restarted.
Also run on the same hardware windows serves less clients than linux. Sure
this again is not the reason for IBM choice, but this might be a good
additionnal reason for personnal use (of course provided SW is available).
