I have a notebook with an 80 GB HDD, which I feel is too small to partition, yet still have Windows run a lot of other programs/games. However, I also have an external HDD (Seagate 160 GB), that I tried installing Ubuntu Dapper Drake on, but Ubuntu gave me a pain in the butt, so I aborted that approach. However, Ubuntu does seem to catch onto SD Cards rather easily. Unfortunately, I only have a 1 GB SD Card, which would be too small for anything to install on it. However, I notice that there are such things as 4 GB SD Cards, from what I saw. Do you think that 4 GB would be enough for Ubuntu to install on an SD Card as a second OS off-site (because there's no way you can have two internal HDDs on a notebook).
