Don't have a N900 - only an N810 and an N800. really want a N900, but don't like the smaller screen, and no navigation, and the fact theat the wife would kill me if I dropped 500 notes on one! Cannot help feeling that it's just a faster N810, and suffers from the same half-hearted, and half finished feel that earlier versions have.

The N810 is my main device, and is used for the following..

MP3 playing with Canola as the whole library random mode is so easy, and with mplayer as the back end it supports A2DP nicely, so I can use my stereo bluetooth headphones. Oh yea, podcasts and internet radio as well.

Web browsing, microb.

Email ( modest - default using gmail via IMAP)

Twitter - Mauku

Xterm - for SSHing to my Mythtv server

Mplayer - for playback of transcoded recordings from Mythtv, and DVD rips.

Built in chat for Gtalk, MSN and now facebook chat.

OMweather for weather (what else!)

Maemo Mapper for moving Gmaps displaying live traffic information

Wayfinder, for when I need Sat Nav

Flipclock - for when I need a large time display

OSM2GO for mapping my local area to add to Openstreetmap.
