Okay, I'm coming from an Iphone an am using the Droid as a business user, so I rely exclusively on Exchange integration.
Pros -
Screen - LOVE the screen! The resolution is double that of the Iphone and looks spectacular, it's undeniable.
Faster task switching
Most apps I used on the Iphone are already on the Droid platform so I am not missing much at all (although I do miss my native DirecTV app)
Cons-
- Exchange integration is pretty awful
- Global address list will not sync (iphone did this)
- Can't move emails to sub-folders (iphone did this very easily)
- Folder list is not nested as in my exchange inbox which makes it very hard to navigate (again, iphone did this perfectly)
I am aware of the Touchdown program which sort of replaces the native mail application, but I refuse to pay money for something that should be built into the phone. If they can update the Exchange functionality I will be in heaven.
