I have been working with Flex for 6 months and I am pretty impressed with the robustness of the platform for developing internet applications. I will certainly port my code for the Apollo platform because I will use the local file system access , clipboard access and perhaps a boost in speed. I can see a lot of cool/useful internet apps that could be built on Apollo and quickly installable for any platforms.
I'm not convinced users want to download and use internet apps. This seems contrary to the whole ajax/flash trend of building robust apps in the browser. The browser is the platform.
Yes, I know it's pre-release, but I was more wondering about what opportunities a platform like this might provide (even if the answer is "none").
