I'm kind of in the same boat. Just got back from a vacation and a long drive, which I used waze on my n900 a lot. I highly recommend this app/service. Not GPS so much, but crowdsourced speed trap reporting!

Unfortunately, it fell off the dash a few times and now I have the dreaded "loose USB". I'm totally up for fixing it but I still feel I should probably move on.

Webos is beautiful, but withering. No point.

I really wanted harmattan, but the mixed feelings on this board, the lack of a price drop or change in availability, the fact that I have to pay for it unsubsidized, and while the community is optimistic, it isn't as active as I would have hoped. It's really just a splinter group of n900 developers.

Iphones are pretty useful as long as you stay withing boundaries. And you don't care about dropped calls. They're pretty, but they're also fragile.

Androids are a mixed bag. They usually have the latest stuff, but are lacking somewhere else. It's a crapshoot. You are going to inevitably hate your phone within a year or two and that was the plan all along. Go buy a new one, see you again next year when you're sick of this one.

I don't really know anything about wp7 and hate elop's decisions, I even hate the entire idea of .Net as a language. But I'll be damned if I don't still give kudos to Nokia on build quality. I may hate wp7 for as long as I own it, but at least the thing won't break...ever. It's either wp7 or Symbian for me, really.

In short, I think I will get the 900 when it is released. Flame on.
