Well personally I plan to firstly get back into being a Amiga user, I spent a little time in Aros, and I have a nice emulation set up in Amiga Forever but I not really had the time or the incentive to really devel deeper into Amiga for awhile, but I think that will change with the X1000.
I hope to try and learn 3d, either in a classic amiga program or blender, it something I always wanted to get better to grips with. Maybe do a bit of programming nothing big but hope to get Hollywood and maybe do some little projects I have in mind. A little bit of graphics design etc
Then the basic general computing stuff like, lesion to the radio, surf the net, check email, go on IRC, play some games, watch the odd video etc. just doing stuff like this but instead of having to do it on a windows machine / environment I will be able to do it all in an Amiga environment.
