For most photographers I would say any high-end SLR is over-rated, mainly because a medium- to low-end SLR from the same manufacturer will do 99% of what 99% of most photographers want to do 99% of the time. This is not to say that high end SLRs don't have their place. They do, especially with professionals for whom that 1% difference truly makes a worthwhile difference, or perhaps a few non-professional photographers as well, and it's not to say that I would not like to have a high end camera (like a Canon 1v for example). It's just that most of us can get by just fine with a lesser camera. A case in point: I have a Canon 7ne (which itself is more mid-level than high-level) that I seldom use because in my hands my lowly Canon T2 is easier for me to use, and it's smaller, which is something I like.
