I think the droid looks better than the N900, it's slimmer and larger screen.

But I still prefer maemo over Android, most android apps are java based, and access to the command line is not as open as maemo. And with the N900 I get the Nokia build quality, the Nokia specs which means a good camera, good GPS, good speakers etc.

The problem I find with android devices is each device runs the same core OS BUT the h/w depends on the manufacturer - for example the speaker on the HTC hero is crap and it's only mono. Droid has stereo and is better.

Android is more and iPhone competitor and as such very simple and easy to use.
