IE9 was built from the ground up to use technologies like DirectWrite, GPU Accel. etc. Porting all these to XP would not be trivial. I guess MS wants to nudge people off that platform so that software can start using new technologies instead of getting stuck in 2001.
Anyway, they supported it till IE8 and MS has one of the best track records for backward compatibility(if not the best) in the industry. Just see Apple to see how quickly things are deprecated.
I am sure developing IE is an enormous cost since MS has to be careful about not breaking corporate software. The benefit to them by making it for OS X and Linux would be negligible or even negative (how many would even install it? Most run those OSes because they don't like MS).

Indeed, hence why I asked why not design it to work (even in a limited form) with other platforms from the off. I realise going backwards now is not really possible what I was questioning was the original decision.

Couldn’t they plug in the past DLLs as other apps do so as to render as if it were IE6 under XP(SP2) or whatever?

OT :you say "Most run those OSes because they don't like MS". Do you think this is true? I'd have thought the majority run OSX for [perceived] usability or possibly lifestyle reasons and maybe Linux for price reasons. Personally I run Linux based on a mixture of ease of usability and price. Despite being vehemently against MSIE (due to time served web developing) I thought MSIE8 was quite good and should it be available for my distro I'd give it a trial despite being pretty entrenched with FF. It's not really me that I'd see them marketing too though.
