I'm working on a productivity software startup which is currently working on the flagship product. In the interests of starting small, I'm targeting the platforms I have easy access to: x86 Linux, AMD64 Linux, and Win32. My dev machine allows me to test x86 Linux and AMD64 Linux builds, and I have been building binaries for Win32 and doing basic testing under Wine, with plans to test on a real Windows system using AWS or similar. A service like this would make it easier for me to support Mac OS X; to build for OS X, I would most likely try to set up a build VM on something like PureDarwin, and test on something a real Mac using a service like this. That said, I don't think there is a good reason to hold back my release for Mac, so it would probably be worth waiting, and if sales go well on other platforms, I would probably be better off investing in Mac hardware.
