Wow, tough question. Really too hard to remember because I'm obsessed with buying redesigns. But I like it, so I'll try.

I don't know, that's off of the top of my memory, cause I've seriously owned so many versions of so many systems in my day. I owned multiples of the PS1 as well, like the one that had composite cables vs. just Sony's input jack.
I've never owned a Phillips CDi, or Jaguar.
As far as handhelds go, I owned every version of Game Boy, a Game Gear, a PSP, PSP go, 1st DS, DS lite, and a 3DS.
Never owned Turbo Express, Lynx, or DSi or XL.
I still own all of them and have never really had a system fail on me.
