Everything is running really well for me. The only time I notice any sort of lag is when I wake the phone up after it has been asleep for a long period of time. Once I have had it on for about 10 seconds it seems to wake up and run right. I still get a little bit of dialer lag if I let the call log go for a few days, but clearing fixes that. The only other problem I have had was with the HTC battery widget killing my battery. Once I kicked that to the curb and starting using a different widget, my battery life is a whole lot better.
