I pre-ordered my N900 unlocked from Dell $453 shipped. Still a little more than I would have liked, but close enough.

I plan on using it with a pay as you go plan initially, we'll see from there. I figured at that price, I could re-sell it pretty easily IF Nokia (or someone else) comes up with a reasonable tablet sized device in the near future. Probably shouldn't lose too much money on it that way. Or I may just keep it, even if it isn't quite what I'm looking for.
