+1 for the lack of MA and 96% VF coverage, quite significant 'flaws' for a camera in this price range.
It's not clear from your post which features you need/what you like to shoot and which lenses you have, but if you are an existing Rebel user and want to upgrade, I agree with the others suggesting getting a 7D instead. It's a more complete camera and a bigger jump from a Rebel, I would go for that. But it costs more, obviously, but it's well worth the extra money especially if you want to shoot sports.
If this will be your first DSLR and you are concerned with 60D's 'old age', you could always get the rumored 650D (which is about to be released in February and will be available very quickly) and spend more money on some decent glass.
For better IQ, this is far more important
than a body with more features (and in this case, basically with the same sensor).
You probably already know that the Rebels lack quite a few features (no big dial at the back of the camera, max shutter speed limited to 1/4000, more shutter lag, slower burst rate, only one cross-type sensor, smaller pentamirror VF, worse battery life, etc...) but the 650D will most probably have the same 18MP sensor which means basically identical image and video quality, if not with slightly better low light performance thanks to the new DIGIC V.
The 60D is a fine camera, nonetheless. It has a lot more to offer than a Rebel but is also priced accordingly. It all comes down to what you need and what you don't.
Good luck with your decision
