I think that the people who are "disappointed with the IQ from this camera" (the 7D) are likely just the pixel peepers who expect perfection on a computer monitor that can only resolve at 96 or 72 DPI..far from the minimum acceptable resolution of any decent print - the human eye can see the pixels(dots) at up to 250 DPI...so using a computer is not the way to judge "IQ" (and as I have said before...people who pay for photographs not only never "pixel peep" or even get a chance to in general since they buy prints...but they don't pay for IQ..they pay for Quality Images...(QI?).
I am surprised when I read that people seem to think the 7D is a complicated camera to learn how to use since it is more feature laden.
Any dSLR will seem complicated to someone coming from a film camera they are really computers as compared to mechanical boxes.... but it really doesn't take long to make the adjustment.
As for the 7D being more complicated than any of the other Canon dSLR cameras, I didn't find that at all when I went from a 40D to the 7D. Yes, it has another couple of buttons (and thankfully loses the useless print button and replaces it with at least a somewhat if not completely necessary button), but these extra controls make the camera easier to use IMO....they are essentially just (programmable) shortcut buttons that let the owner quickly make adjustments that would otherwise require going into the menus.
I think ANY digital camera may seem confusing to someone (like me) that came from a background of mechanical SLR and range-finder cameras. I think I had the most trouble learning to use the SX10 IS I bought before I bought my first digital SLR (40D). The instruction manual was close to 300 pages...same as the 7D.

Some people submit photos to stock agencies. Those photos get reviewed by someone before they are accepted. One of the first things those reviewers do is to zoom in to 100% to see if the image is in focus. This is way more scrutiny than is needed for most applications (I've printed out 24x36 photos from my 6.3MP 300D and been extremely happy with them) but it is the reality for some people. With that reality, getting maximum sharpness can be difficult (especially with the 7D apparently) and can be very important as well (you can downsize to make a photo appear sharper at 100% but you get paid less for smaller images so every pixel counts).
For the vast majority of users though, this may not be important. Try to convince someone to not zoom right in though. Very hard to do.
