I'm writing this post on the Droid phone I got last week. In part, the post is a training exercise in typing with the physical keyboard-- which is either unfamiliar (which would explain my current awkwardness with it) or unwieldy (which would explain future awkwardness in using it).
Overall, I'm delighted with Droid. It's much more reliable than my kludgy Treo 755P. It synchs with my work email like a dream, the display is stunning, the web browsing works great, the apps are fun, and the camera is quite nice (ever since an update was pushed to the phone that fixed a focusing bug).
There are some annoyances. As noted, the physical keyboard takes getting used to - sometime the onscreen keyboard's just quicker to use. The built in apps have quirks -- for instance, the email client won't do signature lines, and the calendar won't let you swipe from month to month. But overall I like my lil' Droid.
