I have both the N800 and the N810 and plan to use them for awhile. Use mine mostly for listening to Old Time Radio shows on an application I developed called otrplayer. Also track my car mileage on my Car Mileage Calculator (mileage). Other than that do some web access but run out of memory fast on some sites. Also use to read my email on the go. Use mplayer to capture mp3 streams that I wish to record to listen to at a later time.
