Not to mislead anyone, I don't own a 60D, so I can only address the second question.
I totally agree with mattwilliams about the articulating screen. The 175-degree limited fold out and the lack of micro-focus adjustment are the only two deal breakers for me. Otherwise, the camera is very attractive on paper, and handles quite nicely in the store, even just after handling the 50D and venerable 7D for comparison. It's light and compact, yet it doesn't feel like a toy to me.
Kudos to Canon for bringing back the interchangeable focusing screens first introduced in the xxD line with the 40D, but which are shamefully lacking in the 7D. Some early 7D reviewers believed that the transmissive LCD overlay prevented the use of user-interchangeable screens, but third party screen makers have shown this to be false. All my gratitude to them. Whether they influenced Canon or not, the 60D has both user-interchangeable screens and LCD overlay. The more viewing and focusing options, the better.
Autofocus will sometimes fail. That's why "L" lenses have full-time manual focus, because many people will need it in a split second. I do. That's when I need a ground-glass focusing screen that speaks to me. I will trade the brightness of the autofocus-optimized stock screen for the accuracy of a manual-focus optimized screen any day. And Canon, how about micro-focus adjustment to make up for manufacturing variances among body and lens components?
The articulating rear-panel LCD screen on the 60D feels well constructed, but limited in movement. Some might argue that the 175-degree screen position can be gotten used to. Not by me, unfortunately. I have a six-year-old Panasonic video camera with this design issue. I have never gotten used to it, and vowed long ago never to buy another camera that is like this.
Canon, why hold back on those five degrees which could really complete the sublime experience of shooting with intuitive symmetry?
