xp last update was in 2010 or 2011, so it doesn't make much sense to loose too much time on it. I would have kept compatibility but virtualbox removed direct3d support for xp in 6.1 because of a big security hole in their driver, I would have preferred that they would simply add a big red button to click to allow users to install this despite the security hole, but they just removed direct3d support, so it's impossible for me to run any version of raine in xp in virtualbox now, so too many people want xp to disappear.
On my end I quite liked some custom xp editions like tinyxp : small, fast and efficient, but oh well, I guess it's too outdated now.
And it's not hardware obsolescence, you still do what you want with your hardware, you can install something else on it, it's software obsolescence only here.
And the next victim will be win7, but maybe I won't have to deal with that... !
