Develop on Windows or Mac?

[Graham Samuel]

I need to deploy my apps on Mac (pre- and post-OSX) and on PC. I also 
work in two locations, with the most suitable (fastest, etc) 
development machine being a Mac in one location and a PC in the 
other. So I have to keep switching development platforms even within 
a project - I just cut a CD on the machine I'm using and take it to 
the other location. Frankly I am amazed at how easy this is - I can't 
say I have ever had a significant problem arising just from switching 
development platforms. AFAIK only RunRev offers this - and they've 
made an excellent job of it.

OTOH I find I absolutely **have to** do my late testing on each 
deployment platform - you can't really debug an AppleEvent handler on 
a Windows box, for example, and the font and font size problems 
others have mentioned often seem to call for hand tweaking on the 
deployment system. Then there's the menu bar issue: RunRev's built-in 
method of hiding the Windows-style menu bar by cutting off the top of 
a window is not appropriate in some cases (for example when you're 
desperate to use every pixel of height - happens when the user 
demands a VGA screen size - yes, some still do!), and I've also had 
to tinker with the Registry (thanks to advice from this list) in 
order to make sure a window fills the screen but doesn't overfill it. 
Et cetera. I really don't see how one could produce an industrial 
strength app on any platform without at least some testing and indeed 
debugging on that actual platform.
