So Called Better LCD on the 40D

IMHO, when you have to move buttons to make room for it, it's obscene. The 30D was ideal in size but not resolution.

I wish my 40D's screen can have the same resolution as my nikon D80 -_-

3" is just as good as 2.5" for me. I only care about the histograms and make sure my composition was ok

The LCD on the 40D is fine. I use it very seldom, mostly to check for a blown sky so that I can add a darker ND filter. Sometime I may check the histogram.
If I do look at the LCD on the 40 then I'm happy with the larger size.
