If you like the bike, go for it. I used to have this frame http://archive.giant-bicycles.com/us...04&model=10953
and I loved it. I wish I still had it(UPS lost it), but I didn't care that it said t-mobile on it. I actually had some really cool comments on it, because you don't see many of them around, it is a unique bike.

If you like the bike, go for it! Don't let what others say about the logo change what you like the feel of. Right now, it is important to get the best bike for your money that you feel good on.
