I am 18. I am a poet and small-time artist so I use the N900 for recording ideas - I constantly get them, so the N900 is the perfect device for getting them down on record somehow, either by writing or voice record or video.

Other than that, I use it for internet browsing, getting information, email, all communications - IM, SMS, telephone - camera, mp3 player. Further, for all the various things it's applications can do - like calculator, time measurement.

Oh, and last but not least - porn!
