The main problem with the 60D is the name. If they had called it a D600/T3i no-one would have complained.
People were expecting a continuation of the xxD series, but that is not what Canon delivered. By lowering frame rate, removing Micro Adjust, removing PC socket, switching from CF cards to SDHC cards, keeping the same focus system as the 40D and switching from a Magnesium body Canon has removed the 60D from the prosumer ranks . Now it is just a consumer Rebel with a different name.
The 60D is not a bad camera, but it is one that I have NO INTEREST in buying.
My 40D is a great camera, but, in hind sight, I'm really sorry that I didn't buy a D300.
