I'm currently in looking to buy a new monitor for my new dual 1.8 G5 computer. Which monitor should I buy for my new system?? New Apple 20" Display New Apple 23" Display Old Apple 23" Display Samsung monitor (please specify model for this one) Sony Trinitron monitor (please specify model for this one) Is the new 23" Apple Display worth the extra $600???? What is the difference between the 20" and 23" that makes the price difference so big? Will the old Display work on my G5? How much are the old Apple Displaays going for and where do I get them if I go that avenue?
