Does it have to be a platform for creation? I use my phone as a sort of amalgamated media consumption device. I listen to music and audiobooks, track my fitness, read (research) papers, I use it for navigation and maps and of course for communication. I don't want to 'create' on device the size of my palm because it's a poor form factor. Fundamentally I want something in my pocket that I can query to find information quickly. This is truly sci-fi terminal stuff and we have it today. Tablets - yes, this is a big problem. It annoys me that I can buy a tablet with great CPU power underneath, but I can't do any real work on it. Real work being development, access to a non-emulated terminal. We're getting closer to this with the MS Surface since you can run desktop applications on it, but I would never buy an iPad or an Android tablet because to me it's just a big phone without the data contract.
