Thanks for the response Mike; it seems we are more in agreement that disagreement.
Like Janis I have worked with both Windows and Macs and their associated S/W. It didn't take long to work out that the differences don't really matter; both platforms can deliver the goods and both can access S/W that will deal with the job in hand. In some ways the most important factor is familiarity with what you are using so that you can get the best out of it. The only exception to that may be for the user to be sure what it is that defines what they'd describe as "a quality end result" as that can often come down to personal taste - right down to preferences to the way something gets you there in contrast to where "there" is.
