So most videos, reviews, and threads I've seen focus on the computer side of the n900 and that's great. However, because I am also buying the n900 to replace my phone (a simple clamshell) I'm also interested in what phone aspects the n900 has.

1) Ringtones

Is it standard mp3 file you select? How many can you designate? For example, can you have a ringtone per person (if you really wanted too?)

2) Voice dialing

I read a post on here that said there was a lack of voice dialing on the n900. Is this true? Even my free phone I got a few years ago has basic voice dialing (with names) though it probably only works 1/4th of the time.

3) Comfort

How is everyone's experience when holding the phone up to your ear for prolong periods of time? Say 30 minutes to an hour? (yes I know you can also use headsets). I couldn't imagine holding the n800 up to my ear for hours upon time (granted I know the n900 is smaller but it is thicker).

4) Voice and sound quality

How is the microphone on the device?

Thank You.
