I already know the good and bad about Droid:

+ Sweet 3.7" screen with perfect aspect ratio for movies (less black bars)
+ A lot of practical apps and good phone centric integration
+ Google apps work great- especially Nav and Layers
+ Game emulators work very well (from a game nut perspective)
+ 3G is amazing in KY (of all places)
+ Solid build

- Android
- Processes reopen even after killing them with task manager- bad for game emulators and I can tell when it happens. For some reason, even apps like Tunewiki will load without prompting-odd.
- SD card stuck behind battery
- 28 less usable gigs of memory compared to N900
- No FM receiver or transmitter
- Have to convert video files to MP4
- No Flash until July (at best)
- Camera is weak and maybe not all issues can be corrected through software.
- Low apps space. I currently have 181mb free on the Droid I am using, which is not much if decent commercial games were to come out.
- Keyboard is weak.
- Sound quality is weak compared to G1 (good sounding device)
- OS updates are at the mercy of Motorola - this is not good, based on their history.

N900 will have to be looked at differently, since "new" OS with version 5 and will take time for apps and phone features to build up and / or improve.

UPDATE: Laughing Man, I did not know that. I have not used it for much calling since I still have my G1 and want to keep my current phone number. I have only called out a few times testing the signal in remote places.
