I think that I've read about Construct 2 for the first time on appmobi's website, where it was listed first in the free HTML5 game engines/editors category.
Glad I heard about it before losing more time with other solutions, which to my opinion are all (both free and commercial) inferior to C2 for simple & rapid cross platform point-and-click/touch game development!
One suggestion though:
Since it is still beta as all HTML5 stuff is, you should make it at least partly opensource (maybe via a higher-priced "partner" license with access to source code), so that it can be improved by advanced users/developers based on their needs without having to wait on a new release for a specific feature to be added.
I'd be between the first to buy it, if the price remains accessible.
