I'm willing to help any PPRuNer with a Mac query - I've been using them for years both professionally and at home, and like Danny, see no reason whatsoever to move to Windoze.. in fact the Mac platform is more successful than ever right now; it is setting the agenda and leading the industry.
Email me at the address shown in my profile.

PS Danny - a great deal of scientific applications are catered for by the Mac - e.g. a Geneticist friend of mine runs a highly sophisticated DNA Sequencer on an ancient Mac LCIII I gave him
years ago!
