I know there are a lot of threads on the Intel switch, but this topic is really interesting to me. I am not at WWDC (obviously), but it seems like even within the limited scope of the keynote, which is not under NDA, a lot more information about Transitive and Rosetta Stone has become available. Did anyone understand, does Apple plan to encourage developers to provide Universal Binaries more or less indefinitely at this point? Would that mean that (with corollary speed hits) PPC-based Macs would be able to run Apple software for the foreseeable future? It sounds like the Universal Binary is not exactly like a fat binary as previously discussed, in that rather than having two processor-specific embedded binaries, it has a processor specific one and some kind of bytecode one, much in the way of Java, that can run on Transitive's layer (aka Rosetta Stone). Anyway, anyone care to join in the speculation on this specific little pebble in the keynote?
