I just wanted to say that I love Crunchbang. I run it on all of my Asus netbooks. Some only have a 4G solid state drive and 512M RAM, but it runs great. I can install Crunchbang, Wine, and all the applications I need, and still have almost 1G free space left.
I hope BunsenLabs is successful, and doesn't become to bloated to run on a netbook with 4G of storage.
