The larger screen at the back of the 450D is the most immediately obvious change but the differences run a lot deeper than that.

The 14 bit processing is especially impressive--never would've expected that in a Rebel. Spot metering as well. It also looks to have finally improved the grip with some better rubber all around.
Oh and by the way. The ISO button finally at the top! No more taking your eyes off the viewfinder to change it!
