Flashlady, re Mac vs Windows. I think one reason why few Windows designers test their material in Macs is more due to cold hard numbers. PCs outnumber Macs by some yet to be identified number so PC users have less access to Macs than Mac users have to PCs. I, for one, never touched a Mac until a recent class at my community college. And I did not particularly like the Mac, mostly because I had to do all my coding via telnet because anything I created on the Mac I could not figure out how to save into a format my Windows machines could read. My brother, a professional designer/troubleshooter, by contrast has told me that the more he learns about Windows, the more he appreciates Macs. Aside from that, I've heard of simulators that enable one to use Linux or Mac programs on Windows and vice versa. I'd like to find out more about those but so far I haven't had the time to pursue that option.
