Thank you all for your answers. I think the best option for me is to go for a Mac. I like programs like Showgirls, Mplayer (works better than SMPlayer on Linux), Transfer, MLDonkey (don't get it working on my Linux) etc. They are simpel en not overloaded with options...
And I need to read my SFS-partitions for a lot of data. (Is there a possibillity to read them on a linux-machien?)

Again, thank you all, Tom
