Dual core, loads of ram and internal memory.
Thats about it, everything else is poop.
Really...
1-ANNOYING REBOOTS...
2-Extremely fast graphics on the 4s... Games and videos are amazing.
3-Apps run faster..
4-From shutdown, the iPhone4s boots up in 30 secs... Evo more like 2 mins...
5-How about battery life? EVO has none. iPhone 4s lasts all day..
6-Camera and camcorder on the EVO are a pile of dawg poop... If you don't have perfect daylight, the pics are horrible... The iPhone 4 with 5mp took better pics than my EVO. Now with 8mp and a new cam on the iPhone 4s.. Fogetaboutit!!!
7-Screen... Give the EVO the size advantage here but that is it. I am already used to the iPhone 4s screen... Retina display has better resolution and it's especially better outdoors in bright sunshine. I could barely see my display outdoors...
8-Annoying re-boots.
9- Lousy memory... I had maybe 25-30 apps and it was always giving me the low memory warning...
10- iOS apps have a more refined finished edge to them.(not an EVO thing, more Android)
11-Only thing iOS does not have is a decent navi app... Or at least I have not found one... The Navigation app on the EVO was amazing.
12- Did I say annoying reboots?
I enjoyed my EVO, but it ain't no iPhone....... Fire away!!!!!!!
