Have you held either of them? There is a totally different feel. I think if you got the 650D you'd always be a little bit disappointed.
Also, I'd say very important is a speed light. I just got the EX430 II and I absolutely love it. Totally transforms your indoor photography.
I have held the 60D yeh and I liked the feel of it. Never held the 650 no but plan on doing so when I go to the camera shop.
There won't be much difference if any to the quality of photos from each camera will there?
The 60D appeals more as it is a camera I think I could grow in to more and will last longer before wanting to upgrade.
The touch screen on the 650 is probably a nice addition but doesnt really scream 'buy me' just because of that feature.
