Right, my collection isn't as big as some posted here, but I still like it.
I would still want to have a ZX Spectrum of sorts and a CD32 somewhere but anyway, here's the list:
Have owned:
1x C64 - Bought '89, Sold in '93.
Several PC's - Bought '96 and later. Sold/gave away most of em.
1x Gameboy - Bought '99 IIRC. Mario/Zelda goodness.
1x Playstation - Bought 'right after the pricecut'. Spend hours on FF VII.
1x GB Colour - Bought '01 IIRC. Coloury goodness. Tiny R-Type!
1x Gameboy Advance without Backlight - Bought 'when new'. Where's my character? I can't see!
Own, roughly in order of 'currentness':
2x C64 - Never sell Commodores. You'll end up with double the ammount!
2x C128D - One on my desk.
1x A500 - Bought in '91, works but the memory expansion died.
1x A2500 - Bought in '02. Actually, the label says so but it never had the extra cards.
1x A600 - Bought in '04. On my desk, needs a memory expansion because it sigh died.
1x A1200 - Bought in '95. In tower, with Blizzard 1230-IV and some HDD/CDRom.
1x Playstation 2 - Bought in '02. R-Type Final Rocks btw. So does Rez.
1x Gameboy Advance SP - Bought 'when it came out'. FF Tactics was nice, Castlevania rocks.
1x Gamecube - Bought in '03. Resident Evil 4 Rocks. Metroid Prime gives me motion sickness.
1x XBox - Bought in '04. Surprisingly little use for this one. Outrun 2 is nice from time to time tho.
1x Sony PSP - Bought in '05. Impressive device! Daxter & Lemmings rock. GTA ain't half bad.
1x Pentium IV (640) PC. 2GB ram, 160GB HDD, NVidia 7800GTX & Soundblaster XFi. On my desk.
The consoles where mostly an attempt to get 'Commodore Style' twitch games back in my life -which failed miserably, I ended up playing all the RPG's instead :-P-.
These days I just play on the good old Commodore's themselves when I feel the need to be destroyed by Project X -no special edition here-.
