Yup, but none of the current nor even any from the previous generation (I did, but not anymore).
Today I own the following consoles:
Nintendo Entertainment System
Super Nintendo Entertainment System
Sega Genesis (original model)
TurboGrafx-16
Sony PlayStation (original model)
Nintendo 64
Sega Dreamcast
After the Sega Dreamcast I bought Microsoft's XBOX, then later I bought the Nintendo GameCube, but eventually I sold both the XBOX and the GameCube along with my original Dreamcast (and that Dreamcast was my third, since both previous ones ended up malfunctioning and over-heating after about three months). Then a few years later I bought a second-hand Dreamcast again, and that's the Dreamcast I own now. Also, with the exception of the TurboGrafx-16 all the consoles I own are second-hand ones bought from eBay, because I never kept my consoles back in the days, with the exception of the TGx-16 as mentioned since it was my cousin's, and he eventually simply gave it to me (that was only a few years ago, not when the thing had real value).
