Hmm, I'd be surprised if Sony dumped Microsoft and embraced Apple - for a start, they're competitors in the premium gadget market, and they hate them for the iPod. Moreover, Sony's corporate side still seem to be chasing the idea that they can be both content providers and market leaders for content players, so have a privileged position to be able to define standards for DRM and control the market for maximum profit. Sony famously hate Apple; pretty much none of their gadgets work with OS*X deliberately, the best example being Minidiscs.
But I'd love it if they'd play sensible, which really just means Sony using open standards and not deliberately obscuring or even encrypting protocols. They produce some fantastic kit. Open standards would mean letting those dastardly Linux pirates being able to use your products too of course.
