Other thoughts after a couple hours of setup and playing around:
1. The bloatware isn't actually as bad as I thought it'd be. I've simply hid the icons I don't care about for now and once this phone is rooted (praise any developers who help that cause, btw) then they'll get removed. I didn't see too many processes running in the background so I don't think it's a killer right now. As well, a couple of the apps I might actually use for the time being. The "Smart Actions" app seems pretty cool actually and I've already setup a couple actions for low-battery and nighttime power savings. I actually might get into Madden and the golf game they put on there in due time to test out the sweet graphs. I like that Swype comes preinstalled - even though I'll predominantly use the physical keyboard, I figure I should ease myself into the soft keyboard over time since this might be the last slider we ever see (You better enjoy it fellas).
2. I had to download a separate APK to get the default "Google News and Weather" widget which I loved from the web. Works great.
3. Downloaded the latest APK for N64oid and it runs incredibly smooth for an N64 emulator on a damn phone. Way more stable than on the OG (of course, I did notice the app has been significantly upgraded since I last played with it on OG)
4. I was really scared when I first ran the "Slingbox" icon that was installed on the phone and it came up with some nonsense about VCast. I feared that maybe Verizon was limiting that application on 4G unless you paid more money. It was OK though. I immediately went to the Market to download the actual version and got in to my home TV with no problem and great video quality over 4G.
5. Miss some feature of Cyanogen already like the multi-colored/sound notifications (maybe there's another app for that but I don't know). Can't wait for CM to get the hotspot feature without additional charges.
6. The camera and video quality is OK after a quick couple tests in a living room with horrible lighting. Some pics were super crisp and had correct focus depths. Some didn't and had some extra noise in there. Video was kind of the same. Still a significant improvement over the OG from what I can tell. NOTE: I'm in no way a "camera guy" like some people I know and can't speak intelligently to camera quality, so maybe this is the best or worst camera of all time, I really wouldn't know from a pure tech standpoint. From a camera tech layman, it looks good but not great.
7. I can't get over how fast the phone is CPU/memory/4G wise coming from a D1. Re-installing apps and syncing data is incredibly fast.
8. Keyboard is excellent. Still don't know why they removed the '@' key though - already got me a couple times looking for it.
9. Speaker is great, similar to D1.
10. On the screen: I think it's just great - no problem here. One comment I made earlier in another thread I think was that I wish Motorola would reduce the bezel width around the screen and make it more flush to the edge. I feel like they could have got a 4.3 in here without increasing the physical width.
11. Overall feel and weight of the phone is great. When I go back to my D1 now it seems so ancient, tiny, and heavy.
12. In general blown away with ease of backup/restore of my various apps to the new phone - nothing to credit the D4 but just android in general and how awesome cell phones are in general these days.
... I probably forgot something, more to come
