I've been using the D3 for just about a week and thought these comments may be helpful for those considering the phone.
I miss not having a keyboard using a DX and I was looking forward to the D3. I use my phone for job site/meeting notes and typing in landscape is fine for me on screen but the text boxes are just too small and hard to navigate. I don't use my phone for games, movies, take the occational photo with it, but basically I need the phone and internet. I'm planning to send the phone back to Verizon within the 14 day trial although I really wanted to like it, there are too many annoyances that may or may not be fixed later. Two years is a long time to be stuck with a phone that has issues from Day 1.
On the plus side the phone is well made. Incoming and outgoing sound are good. The screen icons and text are smaller than I expected compared to the DX considering the screen is only 0.3" smaller. Keyboard is terrific. The pentile screen looks fine to me; it isn't as vivid as the DX but absolutely fine for a phone screeen.
1. Battery is a big problem. I'm not near a charger all day and by 2pm my (extended) battery is very low (15%). I carry a second battery so I can just swap it out but poor battery life is really an issue for me. My DX would get me until about 4pm before it would be yellow. I'm really not willing to adjust the way I work and fiddle with setting all day to use the D3.
2. The battery door is horrible. I'll swap batteries probably three or four times a week and I'm not sure this battery door is going to last.
3. The phone is laggy. There seems to be delays on the home screen. I'll hit the back or home button a few times before I see the screen change. When switching to the home screens sometimes it takes a while for the widgets to populate. As for the icons, not sure if I'm pressing these long enough but they highlight showing they been pressed but I'll need to press again for the action to occur.
4. I've also had at least two calls where I press End Call and nothing happens.
5. I don't mind the blur widgets so much but too much screen real estate is wasted with the widget title.
6. Stupid things like the phone shipping with a front facing camera but gtalk or skype (the two apps on the phone) don't support it. It isn't such a big deal for me but really, this is the no brainer stuff that should work to make it feel like a finished product.
7. The camera app is slow. I got a "failed to initialize app" message after taking a couple pictures.
8. No FM Radio App. I had to sideload one and that is an old one. In NYC we have more stations than the old app has slots.
9. When using bluetooth and the phone is in my pocket, when a call comes in it gets answered automatically. It seems like the screen is activating and hitting "answer" in my pocket. I have the option set to keep the phone off when in my pocket but either it doesn't work or being in my top shirt pocket isn't enough to have the pocket detector activate.
10. Too much junk software loaded on the phone. I have no idea what most of the apps do and all it makes me want to do is root so I can delete it and clean up the screens so I can find my apps.
I frequent the Motorola forums but these seem to be outstanding issues.
