Great discussion here- kudos to all- even the ones slamming me- since I sometimes deserve it
1. Best balanced chipset for 3D ATM is the 3430 that is in the new iPhone and N900. Has both a dedicated DSP and GPU. I was not joking when I posted that I wished the N900 hardware had an Android 2.0 version along with Maemo.
2. Snapdragon leverages clock cycles to make up for weaker 3D feature set. Catch is the 8250 runs hot above 700mhz. The chip was more designed for tablet form factors rather than phones (in regards to running at higher mhz).
3. Like others have mentioned, I too would have bought the Nexus if it had a keyboard, since my beloved G1 is getting a bit long in the tooth. I never did the app2sd thing, since I would use a second microsd for movies. Needed to do this, since game roms and Southpark episodes took up the space on main card
4. I was not ranting except that I wished the Nexus had a keyboard (big time rant there, since I see the trend and it is not kind for Android keyboard devices).
5. Rant two
The Nexus has the microsd card behind the battery like Droid does. Very inconvenient if you swap cards like I did for the G1, but not a frequent issue in my case. HD2 has similar form factor and the card is not blocked by the battery on that device.
6. As far as the resistive screen on the N900, it is very sensitive and I like the precision option of a stylus. Some Flash content is easier to work with using a stylus, as well as Flash games and PC game ports need it too (for some mouse functions).
7. I have a G1, N900 and used the Droid for two weeks. The N900 destroys the G1 and Droid in regards to web content due to Flash, but the playing field will be equal in about seven months or so- IF you have a newer chipset like the 3430 and 8250. Flash will not perform as good on the 7200 series chipset in most current Android devices.
BTW, based on the 3D performance of the 8250 (Nexus), I doubt it will play Quake 3 as smooth as the 3430 (N900) does. Quake 3 plays very smooth with sound on the N900. Duke Nukem does too, but is of course a pseudo 3D game (2D). Respectfully, people that say the 8250 is a better chipset for 3D than the 3430 have not read the specs.
As far as general purpose and the fact that the 8250 has a great DSP for movies (assuming HTC had drivers made to use it) I would have been happy with a keyboard version Nexus. Most game emulators do not need the 3D anyway- need clock cycles.
