I get tired of those sorts of replies. The whole point of the early betas is for developers to get on the bandwagon so that their product works by Windows' launch (along with beta testing for MS of course), thus helping to ensure previously happy customers don't jump to some competitor that do have their priorities straight. I can't imagine how much business Daemon Tools must have lost, for example.
On top of that, given that the RC is now available, all features are implemented and the only code changes left to be made are for issues of a critical nature. If a developer wanted to wait for a stable OS release before fixing for the new/changed APIs/whatever then that's understandable (especially for kernel devs, which Stardock possibly fit into to some extent) but by RC people should really be paying attention.
Anyways, Impulse now recognises Win7 and refuses to install anything on it, so they're obviously aware of the programs that have issues caused by the OS and I would expect are working on fixing them already, especially as Zubaz has stated as such. =]
