Personally I would imagine that Nokia is taking a small (or larger?) hit in USA with the DROID being lauched now and N900 being delayed. DROID will be available earlier and is already getting praises all around the web.

Also I think for larger masses there are few things in DROID that make it interesting, like:
- It's thinner (I would love that one too)
- Better know OS with Google integration
- Capacitative screen
- New navigation software

Though I don't know how the operators and subsidies affect the situation.

I'll end up with N900 though since there's even no idea when DROID might become available in Europe and as far as I understand N900 is far better with multi-tasking which is important for me.
