Sounds like me after shedding my Rebel(300D) and going to a 30D. But I find myself using my XTi a lot now because of it's small size and portability.Now that I am pretty used to it...I havent touched my poor XT.
I really thought that I would want to use the XT at work and the 40D for everything else.....NOT
Part of it may be me wanting to show off a little with my 40D at work
