I'm currently working in a pre-press role with a rather elderly Dual 1.8GHz PowerPC G5 with 3GB DDR SDRAM (and a 19" CRT monitor) running OSX 10.4.11, using CS3 Design Premium and QuarkXpress 7.5. The chap that owns the company isn't from a print background and needs some convincing to upgrade - I'm trying to convince him to replace the Mac with an iMac 27" and Creative Cloud membership (upgrading from CS3 should make it around £30 a month) and Pitstop Pro for preflighting. Can you suggest any arguments to support upgrading? He's notoriously reluctant to spend money and keeps suggesting we get a 21" monitor for the existing Mac instead, and offers useful advice such as "Can't you delete a few things to speed it up?". I'm currently having to rely on my own laptop (which has CS5, Pitstop 11 from my freelancing days) to help me to do my job properly, which seems a bit rich.
