I picked up a 60d recently after selling my t2i to my cousin. The main features that drew me to it from the T2i were:
-audio input without automatic gain control, means I can plug in the output of a recording device to use high quality microphones, or plug a video mic directly into it
-articulating screen, very useful for strange angles
-wireless control of flashes, lots of fun getting my flash off the camera for more creative lighting techniques
-nice feel, larger body
-great kit lens, I got the 18-200mm lens with stabilization, an excellent multi-purpose lens
I love the camera, the extra features aren't for everyone, so I still think the t2i is better value for most people.
