Well, I'm taking the plunge
I've got a fresh OS X 10.5 copy, an external dvd drive, and the cojones to finally go through with my threats against my mini and install OS X on my Mini 9. I have been wanting to do this for a while, but I used my mini 9 throughout my class last year and never found time to do it. With classes starting up again I am re-motivated to rid the laptop of XP!
Giving it a shot probably over the course of a few nights this week. I'll post up with my progress, problems, and hopefully success story!
For those curious, look here for instructions
