RIght now, with the latest firmware upgrades, and based on the comments I have seen in both the Droid and Maemo forums, if you want a phone that can also browse the Internet get the Droid. If you want an Internet browser that can also make phone calls, get the N900. If you want Google integration, get the Droid. If you want Linux integration, get the N900.

If you want it all, wait and see what Dell comes up with in the Mini 5/Streak, what Nokia does in the next firmware release, and what Motorola does either with their firmware or with new models, and then reassess your options.
