So it isn't quite the mother of all phones to end all phones?
Its not being marketed as a phone, fancy that.
http://www.gsmarena.com/nokia_n900-review-421p4.php There is a map application running there, 810 also comes with a gps app, it does your position, favourites, poi, ect. However you got to pay for routing and voice.
There are other gps software available for 810, but I never played with them. On a motorbike its a pain to test it out. Especially in the constant rain that we get here.
Regarding the camera, what do you expect, its a PDA, not a dslr. If I want decent coffee, I would not go for instant one. If I want a good camera, I will go for a dslr.
Looking at the pics they managed to get, its decent enough to make a picture if you are in the middle of town and some unexpected circuis turned up, but for any proper photography, I will stick to a proper camera thanks.
Then half of the review went around complaining about the applications, who cares? Here is the whole point of the OS, you don't like the app, use another one. For 810 there are at least 3 different pdf apps, word processors, file editors, ect. Give it time and it will be ported, you can even try to simply re-compile it yourself, pending what they changed API wise between switching X server, if anything.
You see, this is exactly why I am still saying
don't buy this as a phone, buy this as a
PDA.
