With mobile devices, there has always been tension between having your stuff with you and being able to get at your stuff. I want my mobile devices to do one or the other well, preferably both! With my N800 and a couple of big SD cards, I can carry a lot of music and photos and PDFs. At the same time, if I discover that I need something from my home computer, I can fetch it to my tablet over the public Internet. Because it can talk to other devices over USB, my N800 can ingest stuff from other devices like my video camera and my DSLR.

What I want from the next generation is location based services that I can use without revealing my identity. I don't mind paying for some of those services as long as my identity remains hidden from the provider. The Electronic Frontier Foundation has a good introduction to locational privacy, http://www.eff.org/wp/locational-privacy.
