I have an Atari 800 and an Atari 800XL. Personally, I'd be fine with XE art on all my Atari 8-bit PC games because that would mean that any XE games I acquire would fit right in. Also, well, they DO run on the Atari XE, so it's not misleading. Because "Atari 8-bit" isn't really a good platform descriptor, XE makes a lot more sense.
