I've had my Droid for a few days now, and the only issue keeping me from porting my current ATT (iPhone) number of is the lack of a decent exchange client. The one that comes with the Droid reads and writes emails just fine. It also brings in the calendar just fine, but is severely lacking in a few things: 1. Built in support for reading excel, word and PDF docs. 2. Ability to click on a meeting invite to add it to your calendar. Another function the iPhone does is adding meetings you were invited to to the calendar automatically, but not confirming them until I tell it to. 3. Email search functionality, it just isn't there. There are several other exchange clients, but real reviews on them are few and far between. Does anybody know if there are clients out there that meet these needs? A few of them require a purchase before you install.
