I've always been pretty pleased with the speed of my Desire but I recently bought a Desire HD for my wife and was amazed at how much faster it was than my Desire running Leedroid 2.4.1. Since it's the same processor, from what I read I guess it's the HD's larger cache and better GPU that makes the difference. Now I'm beginning to wonder if there's any way to approach the HD's speed on the Desire. Maybe LeeDroid 3.0.7.
