So I'm just in the process of installing, and I'd been sort of thinking about partitioning, but never got very far.
When I installed Vista, I decided on
60Gb System (Windows + Software)
40GB In case I ever wanted to play with Mythbuntu or similar
430 GB Music
400 GB TV
Have I left myself enough space in the system partitions, and is there any advantage to expanding or shrinking the main data partitions?
