Seriously, stay on windows. Windows 7 is seriously good.
In the hypothetical world where all pro would support unix systems (is in electronics conception etc) it would be awesome.
Unless you like working on your OS more than on music, stay on Windows.
Don't trust those who say it's totally easy. There will be a day when you will have a problem, and will have to open some stupid system files to add or remove a line, and where you will fuck something up, unless linux has drastically changed !
I remember in 2008, just out of the box, i had to open several files and add mounting points manually in the lines to make the internal hard drive permanently mounted, and it took me like 2 or 3 hours because I did know nothing of it at the first time.
Linux is nice for engineering, programming, or if you want everything totally free, this kind of stuff. Otherwise, it's just a pain in the ass for nothing, IMO.
