Yes absolutely. Both Windows and OSX/iTunes have existing desktop/tv mediacenter lock-in they can take advantage of to secure (imprison) new customers. Android doesn't have such a firm grip on its users. The strongest lock-in Google has is their online services like Gmail, Docs etc and even there it's really easy to export everything and use it on a different platform (which ironically is why i am a Google fanboy). I don't know whether Chrome OS/GoogleTV will become a viable platform to allow Android users to easily extend their mobile computing onto the desktop and tv or maybe another Linux distro will steal that opportunity (I recently saw Canonical demontrate some pretty seamless transitioning between Android and Ubuntu). Both Microsoft and Apple are moving towards the cloud with many of their services so maybe that's where the war will be fought, but I don't know if I see the whole app ecosystems moving along with them.
