The EVO 4G is quite a beefy leap in hardware, so let's see here:
* From a purely communication device standpoint, the most basic purpose of the unit, the addition of the front-facing camera opens the doors video chat. First we have the cell phone, followed by some great Speech to Text engines for Emails and SMS, and now the possibility of mobile face to face communication. Excellent! Pair that with 4G WiMax, Boom Goes The Dynamite!!!
*My HTC Hero has a bit of lag at times when not connected to Wifi. I'm guessing it may be something to do with multiple email accounts and calendars set up to sync. I'm pretty sure the beefier SnapDragon and WiMax will end such issues.
* The 4.3 inch screen just may pull me away from using my Dell Mini 9 on flights to watch movies or play games.
