Very good post, something I was asking for
Fixable problem, for example you could just make a tablet with a version of Windows. I hear Windows PDAs have difficulty editing the documents, but still...
I read that IP will be the most efficient medium for voice traffic in the next few years. Widespread adoption might take a bit longer I figure, say in 5-10 years VoIP devices might be the norm. But this wouldn't help with our scenario as the time frame is different.
True in the North Am, not true in parts of Europe, little clue about the rest of the world here. Even in Finland cell phones are paid by the employers for some people, getting the same financing for a tablet might not be that easy.
