Ubuntu preloads in Oz

http://www.vgcomputing.com.au/ will install almost anything on a 
computer they provide, including breezy and kbreezy.

They also rate computers (laptops at lest, that's what I'm looking at) 
for Linux compatibility.

They lack info on Acers though, even though they sell them.

They're located in Glen Waverley, about the demographic (tho not 
geographic) center of Melbourne, but ship all over Oz.
