This is allegedly an 'update', which it isn't when you use two y/o parts. But to each his own. I will wait until they do an actual update that uses new parts.
At least you can have this machine as a laptop without burning your legs, or the fans blow drying your hair haha, i know i have and have had a 13" and 15" MBPr.
This machine truly is a laptop the rest are table/desktops.
As far as 2 year old parts who cares its a 12" not a high powered 15", and my 1.2/512 was $1400 less than the 15" 512 model here. I am not paying $3,500 AUD for a laptop that pretty much does the same thing, i can go to Bali for a month for that.
