Well I just installed 10.04 with decent success (this link is exactly what
I did within the last 6 hours

Main reason for a Linux move is simplly because my industry (Visual Effect
for Film) is moving toward linux and so I am exploring the possibilities
plus the programs we (I) mostly use were developed and built on linux
systems for linux so they tend to be more stable plus I dont care for the
way apple and windows are going with there OS. They are both beautiful but
they are just screwing themselves over on the framework. As for the monitor
if I can find one I will use it but really my ideal goal. But do you have a
preference for a stable linux OS on mac?

Thanks for the help!
