Ever heard of it? No? Me neither... until a few days ago, and man is that distro FAST! It is capable to run it from memory making it even FASTER! Did I say it's also very tiny? Bodhi Linux You can download here the live cd or image for USB stick...
I haven't used that version before. I'm currently using ubuntu 12.04 64-bit. I also use windows 7 home premium most of the time.
