Hypercard clones

There are basically two Hypercard lookalikes, namely Revolution and SuperCard. While both run on MacOS X and Windows, Revolution even supports MacOS System 7, Windows 3.1 and quite a lot of UNIX dialects, including Linux for Intel. Both can convert Hypercard stacks, but somehow both feel awkward compared to Hypercard, and there is no Nine2Five Reports for any of them. Biggest minus for me: no current plans to port them to PalmOS, PocketPC, Symbian60/UIQ or Linux for ARM (Nokia770).
