The resistive display is really good actually. No multitouch, but for me it is nice to be able to use stulys etc. Especially when surfing the web, you can really take advantage of the high resolution and accuracy to hit those links. I hate the zooming/unzooming on other phones.

I think we will get more options for the maps after OVI store opens and Nokia will probably develop the OVI maps further too in the coming months.

N900 is still clearly a work in progress, so you would have to deal with that. On the other hand it is most definitely the platform with most potential at the moment.

If you are a real Google fan you could also wait for the Nexus One. I would think they will try to provide best possible integration to Google apps.
