It might have been said before, but the three big issues are lack of driver support for modern chips/devices, no 64 bit (xp64bit was a dead end, I did try it at the time it came out) and whats a lot of people disregard... security... XP was/is an open door.
So yes, unless you use it on very old hardware or virtual machines (*not* internet connected) ... it's dead Jim... dead...
