At least in our house anyway. As long as I have a nice controversial title to rope you in i'll explain. I spent last night playing with both my parents DroidXs and my wife's Evo all of which are still on 2.1. I can say without a doubt and everyone in the house agreed thier phones run better. Sure my phone scores better on linpack but it doesn't translate to better performance. I think any performace gains we think we have are just imagined. I was in the same boat as many of you. I thought it performed better until I ran them all side by side. Sure mine will play a couple of videos theirs won't but not many. Once you have about 3 different browsers they will play most things on 2.1. If you're on 2.1, stay there.
