I still have my original Xbox from 2003 and I still play it from time to time. It's a great system that still holds up well. I play my 360 more, but my original Xbox still lives on and still gets used. I also still play my PS2 from time to time.
I love my new systems, but I still enjoy my old systems too. I'm actually still collecting original Xbox games because they're really cheap right now. I found some Xbox games at Goodwill for $3 each, so to quote ErnestDalbero, my Xbox is going to be seeing action for some time.
