I am glad to see this thread!
I currently have a Palm Pre and have decided when my 1 year is up on March 18th I will change to the EVO.
The two things I like the most on my Palm are the wireless Tether for free and the ability to block calls.
I use my wireless tether all the time and am concerned about being able to do the same thing on the EVO phone. I know you have to root the phone for the wireless free tether and that concerns me. I am not a phone guru, I did hack my Palm when I got it to be able to tether but the steps for doing that on the Palm were much easier than what I have read, that I have to do for my EVO.
I hope I am making the right decision on change, it looks like a fun phone and I love the fact that my screen will be much bigger!
