Hey,

I wont answer your question on "Why Debian?", but i will say that AV linux is amazing!
I'm really impressed with it because:
- FFADO "just worked". ie: modprobe raw1394, chmod /dev/raw1394, start jack. Record 12 channels at 8ms for 1/2 n hour with 1 xrun.
-XFCE: Although i downgraded to stable (4.4) despite having the testing 4.6 installed, it was not much effort, and not half as bloat as KDE/full gnome.
-RemasterSys: Click the button, answer some questions (that are newbie freindly) and have an ISO made of your exact current system. (I know other distros have this feature, but they never seemed to work so well.
-Wine: For windows -> linux people its great: pre installed. if you dont need it, its only a click away in Synaptic!
-I could go on, but networking, internet browsing, typing (Abiword :-) etc all works well too, installing is a doddle, and if i take a DVD around, i can get my entire system up & running in under 2 mins! (Upload edited files to a git repo on Github when developing, my own site if its an update on music.)

GMac, the "Author" of AV really done a great job in my opinion, very much recommended!
