Just remembered a slight "incompatibility" worth mentioning and that's the uIEC device comes standard as device #9. This conflicted with games expecting the standard 1 drive scenario. Not a real problem... all you have to do is type in a command that tells the uIEC that it really is a #8 device. And it stays that way, even after you turn the computer off or reset. The command is found on the uIEC Wiki page IIRC.
