This is why I think being a fanboy is stupid - no offense or anything.
It's just that when you pledge your allegiance to a certain company, you don't get to experience a lot of great games that come out for other systems. I used to eat and breathe Nintendo - I had all their handhelds at one point and an NES, GC, and Wii. I still have most of those systems, but I own a 360 and a PS2 Slim now.
If my Wii did not stop reading discs, I would not have had to send it in to Nintendo for repairs. But despite their excellent customer service, my system was still faulty when I got it back from the repairs department. I had to send it in again. I was without my Wii for a month. Because I was attached to my Wii, and I obviously had to part with it, I decided it was time to buy a PS2 for backup fun. Wonderful games like Kingdom Hearts I and II, as well as Persona 3 FES are now in my library, and the backwards compatibility of the PS1 that makes it possible to play games like Final Fantasy VII has made this system the favorite of mine.
I also own an XBOX360, DSi, and PSP and they do receive pretty good use. Especially the DSi.
If you're partial to one thing, then you're definitely missing out.
