Hi! I am strongly considering switching from a windows pc to a very good looking iMac G5 (with 1Gb memory). I have some questions / doubts still on the following items: 1- support for dual layer DVDs burning: is this expected to happen any time soon? 2- video memory of 64Mb for a kind of low budget video card, is this really enough to do good video and image editting? THANKS!!!!
