I would class myself as both... I go through stages of playing something then loosing interest and moving on to the next thing, but I could never bring myself to sell any of it. I do have a Jaguar in mint condition, boxed with manuals and another brand new sealed controller which I have no games for... so I have never used it. But I could never sell it.
My lynx is boxed with instructions and warranty card and games too... I have had many hours of joy from that, though it's safely tucked away in a cupboard at the moment.
My amiga 1200 made an appearnce about 2 weeks ago and I bought a few new bits for it, HD cable, more floppies and like... Used it alot recently though I must admit its dying off again and will probably be put away again in another 2 weeks for me to fetch out something else... perhaps the dreamcast, or perhaps I should buy a couple of games for the jaguar... or maybe get out the lynx... we shall see.
