lack of system font size scaling delaying purchase I was about to make the leap from PC to iMac yesterday but the salesman in the Apple Store did not know how to increase the system font. Luckily I came home to do further research before buying, though I had assumed that some tweak must exist for such large screen options. Do you think it is worth risking buying an iMac on the rumour of 3 size choices to come, ie will this be an upgrade for existing operating systems or would it only be available on future machines with a yet to be released operating system? Is there any way of confirming the rumour? I currently use a Logitech mouse (on PC/XP) with excellent zoom features, but from reading the manufacturer's web page FAQs I'm not sure it will work with iMac. If they come back to me to confirm it does then I will let everyone know of this workaround option.
