OSX Netbook

I would really like to pick up a Dell Mini 9 netbook and try putting OSX 10.5 on it. I think having a Mac netbook would be outstanding, but I wonder how the OS would run on the Atom and 2gb RAM. Obviously, I'd have to upgrade the SSD to at least 16gb to fit the OS, which would put the price of the netbook around $350.

Worth it??
