Which distro should I install on my 8GB pendrive? I need it to have powerfull repos (everything, music editing is crushial) and should be lightweighting not losing on functionality. Any propositions? PS: I'm now on windows.
EDIT: I'd like to use XFCE and light-weighting should be priority. I mean I'd like to choose all packages from scratch.

fedora 16orubuntu 11.10for all its functionalities it is based. it has yum repo/apt-get and has all functionalities you needed – harish.venkat Feb 4 '12 at 18:28
