Hi! I´m happily typing this (first post) on my my new 1,5ghz 12-inch PowerBook (totally in love with her). I have several PowerPC Macs but all of them are laptops and i´m planning to buy a powermac for audio work. What would you choose between a Dual 1,25ghz MDD G4 and a 1,8ghz G5, and why? Is the G4 limited to 2gb of RAM? I have considered a dual or quad G5 too, but i´m afraid of the liquid cooling system and the noise (i´m going to record and mix in my bedroom so minimize ambient noise is a must). Thanks for any advice, and please excuse my english!
