I hate to be acting like a droid fanboy here since I just got one a few days ago, but it's worth addressing some of your comments:
I would say the email support is better than all other devices with the exception of the Blackberry (and that is only when it is running an onsite BES parallel to an Exchange server). But what you really seem to be saying is that ActiveSync is weak. I agree. Frankly, what you left off is that the Droid should have been able to sync with Tasks just like a lot of other devices that sync through ActiveSync. Why MS left off a notepad sync, on the other hand, is bewildering.
I like the email app more than the Blackberry interface app. How can you not LOVE the html more? Blackberry is good for promptness but their GUI was awful.
Same goes for the Gmail app...it's a heck of a lot better than the app on the Blackberry. Moreover, I like that it is separate. Indeed, on my Blackberries, I always used to de-unify the messaging because I found it way too busy. Indeed, I had an inbox for SMS, email, gmail, etc. Liked it much better that way. Now indeed, you can argue that you should have the choice to re-unify the messages...seems fair to me.
When I had a unified inbox on the Blackberry, I never could tell which account had email. They all just aggregated into one notification. So what are you referring to?
Essentially, it sounds like email is the most important product for you. Ergo, why didn't you get a Blackberry? They are AWESOME for that. I guess you didn't believe everyone online who said that the Droid didn't live up to the Blackberry in that regard and figured you would have to see for yourself?
