For those of you who prefer the Stock Android Launcher then this is how you can disable it once you get your Evo.

Go to Settings > Applications > Manage Applications
Scroll through the long list until you find HTC Sense
Tap on HTC Sense and click Clear Data and then click Clear Defaults
Then just tap the home button and it will ask you if you want to complete using either HTC Sense or Launcher. Check the box at the bottom to use this action by default, then tap Launcher.

and viola, Sense is now disabled.
