I'm what you'd call a computer trainee. I have shitloads of experience and potential, but not that much knowledge. I have yet to even go to college and study comps!
However, as a Linux user, I really support this. Using WBFS isn't that bad, and even problems in the filesystem itself are no reformat-requiring PITA because of WIT/WWT. However, having an unresizable hunk of inaccessibility (besides installing Wii games) in my hard drive does get annoying.
Perhaps when I'm a dev master I will come back to this! Hopefully, by then, someone will have already done this. Definitely by then, another Wii or two will have been released and I'd be adding extfs to that one.
