I built my first PC, so I could play Fallout when it was released. Before that, I used my trusty old souped up Amiga 4000 for most stuff, including internet.
Being an old Amiga fanboy, I'll say, it had all the advantages of a game console, i.e. one hardware manufacturer for the core computer and the operating system, yet all the flexibility of a personal computer. The powers that be knows I hated PC's when they started to dominated the game market. It was awful, looking at all those inferior games and dumbed down new releases, that had to be able to be developed for both the superior Amiga platform and the inferior PC platform... sounds familiar ?
Once consoles get to the point of being better than PC hardware and having easier to use interface devices, I might consider leaving the PC behind as a gaming machine...
