I don't think measuring the hits on a website would be a very accurate way of measuring a potential user base. I also don't see how the whole product would be different, with proper planning I think they could be almost identical, even down to the hardware. Again, I am not a software engineer, but am seeing it done by other companies who are producing much more complex modeling/animation/simulation applications that are claiming their code for mulitple platforms in almost identical. Alias, Newtek, and Luxology are all doing it.

I agree on missing the fun, and yeah I've got a couple of pcs too. I own a graphic design company and on rare occasion do need to crank one up to test web pages, presentations ... that will be viewed on a pc. Not to hijack a thread, but now I just need someone to convince me on AFPD or Reflex. BTW, I've heard of some Mac users successfully running an interface with XPlane on the Mac. Though the number of rc aircraft are limited, I've heard the simulation is pretty accurate if you tweak with the scale a bit.
