Might I point out that the "PSX" was actually a DVR that also played PS1 and PS2 games. The original PlayStation was abbreviated as "PS" (or "PS1" when it became clear that there would be more).

My first console was a PlayStation, at Christmas 1998 (I think it was then - came with the original Spyro the Dragon, and I can remember buying the second when it came out in 1999). As such, I never actually played on other consoles. Got a PS2 around 2002, then a PS3 on the EU launch day. The first console I played on that wasn't part of the PlayStation family was an Xbox 360 at a friend's in the run up to the PS3 launch.
