Sticking with XP as a primary OS? Well, I recently bought a new GeForce GTX970 card: no drivers for Windows XP.
So that's another reason not to stick with XP any more, as if you still needed any 😀
But yes, I do have some older systems with XP, because if at all possible, I do want to test the software I develop and sell, and make sure they work on XP if at all possible.
I guess it is my vintage/retro-vibe, but even with new software, I prefer to make the software compatible with as wide a range of systems as possible, including older OSes and hardware. Testing against older hardware and OSes can often uncover bugs as well. Besides, I just like the challenge of it. If there is no valid reason why something shouldn't run on older OSes and/or hardware, then I want to make sure it does.
In fact, some of the software I sell actually has some 'undocumented' support for older hardware. Eg, officially we require SM2.0 videocards or better. But just for fun I also enabled a fallback path that needs no shaders, only multitexture support, which I have tested successfully on a GeForce2 card.
