I have an old Netbook that actually runs pretty well on Linux Mint with Xfce (an SSD might have something to do with that). I would love to get BB running on it. I use this little guy as a toy to play around with, but also to troubleshoot with. The idea would be to create a "Blackbox" user.
Also, if there is anything lighter than Mint, I'm open to trying it out if I can use BB with it.
And as I was typing this, I lookup D*** Small Linux... it comes with FluxBox. I think I know what I'll be doing this weekend. >:]
