No definitely not a Nintendo hater, I've got a Game Boy Advance SP and a Wii, although I will admit I prefer Sega's arcade style over Nintendo's style but no I have loved several Nintendo games. I have lost interest in the Wii's controls though and my PS3 gets alot more attention.
Regarding the single format wish, for a bloke like me who works full time and has a young family and whose game time is limited to 2 hours max a night - it would be a god send, 3DO had a nice idea but for single format to truly work you would have to have the current big guys all sign up.
