Nah... he just thinks the Xbox is the best and everything else sucks.
I do think the Xbox 360 is my best system, but that doesn't mean I think everything else sucks. That's the biggest difference between the hardcore gamers like myself and the hardcore fanboys. We never pledge allegiance to any particular system, we just go where the games are. Most of us spring for multiple systems because we recognize no ONE system has it all.
Yes, I'm partial to the 360. They showed a TON of games at E3 that I know I'll be buying over the next year. I even got to play a few of the demos thanks to the E3 at home thing they did on Xbox Live. I COULD only play those games and probably be just fine, but then I'd miss out on all the other good stuff the competition is working on. I have no intention of letting that happen.
Oddly enough though, with the two new consoles coming out this fall, the system launch I'm still looking most forward to this year is still the DS Lite. I plan to get one of those suckers on launch day, so I can play my New Super Mario Brothers game on it.
