so far i'm not totally happy. it's a cool phone overall and it's fast but it's very difficult to type on the keyboard, and the touchscreen .. forget it and you can't use a stylus or finger nails.
Keyboard takes practice. I was kind of bummed out about it when I first got the DROID, but now I like it better than the touchscreen keyboard or my old Treo. No, it'll never be as nice as the Bella keyboard on my desktop, but then again, I actually paid more for that than the whole DROID (we had an extra $100 off, though the NE2 plan).
Touchscreen is capacitive, like that of the iPhone, the Palm Pre, and many other "touch" devices. A capacitor is formed when you have two conductors separated by an insulator.. in the case of the touchscreen, there's a conductive layer, and the glass itself is the insulator. Your finger, making electrical contact with the screen, changes the capacitance, and that's how the "touch" is recorded. It won't work with most stylus (like for older Palms), because they're made of plastic... they are insulators themselves, so they won't change the capacitance. Maybe an all-metal stylus, but the point is to not need the stylus. It's not perfect.. my left fingertips are heavily callused from playing guitar, and that's enough of an insulator to make using my left hand kind of hit or miss on the DROID.
The old-style touchscreens, like the Palm Pilots and Treos, were resistive in nature. You actually had to push into the screen a bit, changing the resistance value to record the touch. This worked ok, but it did require a stylus, and it also caused regular wear to the touchscreen.
I still can't figure out my calendar or how to IM people.
I didn't use a Calendar other than the Palm calendar, so I didn't have any "integration" issues. The default calendar app syncs to Google Calendar, which is nicer than it was with Palm, since I can access this from any old PC, and there's no explicit sync needed (stuff from Google just syncs over the network, in the background).
There's going to be stuff to learn, with any new, non-trivial CE device. You can get cellular IM from contacts, and most other means of communications. Just go to "Contacts", and extend-press on a contact. You'll get a list of icons, including email, SMS, Facebook, etc.
I also use IM from Yahoo, and for that, I downloaded the Meebo free app. Works great. This integrates with the Contact Manager, so if I have a other folks on Yahoo (or other chat protocols supported in Meebo, like AIM), I can get this directly from Contacts, too.
