Movies, music, webbrowsing, irc and development are my main uses, plus I like to use amiga os based systems for emulators (much rawer apis, so in my opinion the emulated machines feel more "accurate" as opposed to on windows where you feel the hosts influence). Im a big graphics person too and for low color 2d per pixel graphics Im a fan of amiga software (dpaint/ppaint/brilliance) over options on other machines. 3D graphics, as much as Id like to be able to say otherwise has become the realm of Windows for me these days, due to raw power and better software (some of the old amiga packages are still quite usable though). I dont think this will change until AROS gets something like Blender, and even that will be a compromise,... some things you really get used to speed with and its painful to go back.
