I've had the Droid for 24 hours and have been able to explore many of its capabilities.
Pros: The large, bright, touch screen. Gestures are easy to perform and the screen responds quickly.
The home screen is actually 3 screens, with the other 2 accessible with a left or right swipe. There is room for 12 application icons on each screen, giving quick access to up to 36 applications. The Applications button gives access to all of the installed apps. It's scrollable so there doesn't appear to be any limit.
Storage is not a problem. With 34 applications and several widgets installed, there is still about 232MB of internal storage left. Pictures, videos, and songs are all stored on the included 16GB SD card.
Plugging the USB cable in doesn't automatically mount the Droid as a disk drive, you tell it to mount via a notification message. Unlike some of the reviewers, I consider this an advantage as it allows me to charge the Droid via USB and not have the device pop up as a drive every time I plug it in. Copying files to and from the Droid is simple drag and drop. No drivers were need when I connected it to my Vista 64 desktop and Windows 7 netbook.
The on screen keyboard is easy to use with a little practice. I find I rarely use the slideout keyboard for text entry.
The browser is very good, displaying web pages clearly. A double tap zooms in for pages not formatted for a small screen.
Once I entered my Google account credentials, the Droid picked up my Gmail contacts. I did have to export my old phone book from the Verizon Backup Assistant web site to a CSV file and import it into Gmail, and then all those entries showed up in my contacts as well. It even merged email addresses and phone numbers when the names matched. There is one contact list for email, SMS, and voice calls. It also picked up my Google calendars.
Setting up an IMAP account for my personal email was a snap.
The GPS mapping application is really nice. John Dvorak may have been right when he said this could spell the end of the standalone GPS receivers
There's even a car mount available for the Droid.
Cons: It takes two motions to waken the phone, one to push the power button to wake it up, and then you slide a lock icon to the side to unlock the screen. I suppose this makes it more foolproof with the touch screen.
To turn the various radios on and off (GPS, WiFi, Bluetooth) requires going into the settings menus and several clicks. However, a Power application solves that giving one button toggling on the home screen.
Voice dialing isn't available with a Bluetooth headset, but that is expected to be added in a future update. I've never made much use of that feature on my other phones so it isn't a real problem
Overall, I really like this phone. Oh, it does make phone calls easily and the call quality was good for the few calls I've made and received. My Jawbone BT headset paired with the Droid with no problems. I haven't done much with the camera yet, but it's 5MP with autofocus. It also takes video. I've installed about a dozen applications, all free so far, and all have worked as designed. A couple I tried didn't work will on this phone, and they were uninstalled. There is an application manager that makes all this easy. I did not install the flashlight app
