I too gave up my PRE for the EVO. It is the phone that I have long waited for. The only thing webOS does better than Android is multitask (I will give credit where credit is due). Not that Android deosn't multitask, but webOS's implementation with card view is way better. That being said, Android and the EVO smoke the PRE and webOS is every other way possible!! When I look back at the tiny screen on my PRE I wonder how I ever used it! All the google app integration and functionality into Android is simply awesome (maps, navigation, earth, sky view, etc...). Have you seen the street view option on Google Maps?!? Unbelievable!! Google Navigation is far superior to Sprint Navigation. Everything just works. This phone hasn't left me with the thought, "If only they would have done this..." The EVO/Android combo has met and exceeded every expectation that I had and helped me to set some new expectations for future smartphone HW and SW.
I started out with the Samsung Instinct a few years back, as it was touted as the iPhone Killer. After a few days I knew it wasn't even in the same ball park. Moved to a BlackBerry and knew right away, that wasn't it either. Had high hopes for the PRE and webOS, but it just lacked the HorsePower (HP!) to compete. Now, with the Evo, I can finally hold a phone in front of my iPhone wielding friends and say, "How ya like me now!" This phone is it!!
