Lol i REALLY think you should reconsider. I have both an epic and and evo and even with cyonogen mod the evo doesnt compare. Youll gain .3 inches and lose amoled for that fugly lcd riddled with backlight bleed and that infamous patch. Youll be downgrading hardware a whole generation... sorry man im sure you dont care but i dont want you do something you WILL regret. Run a search other people here have done it and admit they shot themselves in the foot.

there are plenty that have and loved the change to evo.. and consider it an upgrade in usability.
my sis has an epic. her battery died, so she had to borrow my evo to take a few pics of her daughter...
15 mins after using my phone...
she says as she hands my phone back, "wow, your phone is so easy to use."
things just work better and together...
ex: I can talk on my phone and take a picture at the same time.
there are much more choices in the development community...much bigger than epic.
