A couple of notes from someone who is considering both the N900 and the Droid but waiting to see the Dell specs:

The Droid is underclocked but this will reduce battery drain. It will be interesting to see battery tests of production models.

The N900 might have better DPI but the Droid has a bigger screen with more pixels.

The N900 does have an FM radio but, at least from what I've seen in other threads, doesn't have an app to access it. One hopes this changes.

The Droid has a digital compass and uses BT 2.1 as well. BTW, does anyone know what BT modes the N900 supports besides the "stereo headsets" mentioned on the website?

I'm less impressed with the N900's two speakers than with the Droid's two microphones with noise cancellation.

The N900 has a better name on the lens so I would agree on the camera. OTOH, the Droid seems to have more camera features).

Lastly, given that romanianusa sounds like he's in the US, I suspect that the Droid will be cheaper. As of now, I haven't heard of any subsidized N900s from US carriers.

Still, it's a good list. you earned a bookmark as well as a thanks.
