How long have you had your Evo? My first Evo purchased 08/24/10 had a low power button, really annoying and somewhat hard to press. However, I returned that one for light leakage before my 30 days were up and my new one has a much better power button among other things. I don't know if I just got a good one or if HTC has upped their build quality recently ... but I like the power button much better on my 2nd Evo.
