My experience with Amiga computers set my expectation that computers should "just work." With Amiga running an app was as simple as putting in a disk and playing. Also, the A500 set my preference for integrated motherboards, with gfx and sound on board for less hassle and better reliability.
It was initially a bit of a culture shock when I moved on to PC's to find that you had to fiddle around quite a bit more and (if you lacked a specific type of sound card for example), you didnt get any sound with some games.
Over time, I got used to the PC and came to appreciate the versatility and availability of the hardware. Eventhough Windows can be a pain at times when configuring some games, I'm impressed by how painless software installation has become considering the absolutely vast variability of hardware between PCs.
It'd still be nice to have computers that "just work" though.
