I was looking through what sorts of Windows laptops there are, and I discovered that there are the so-called "Chromebooks", which are essentially harddrive-less laptops where everything you do is on the internet, and I mean EVERYTHING.
This is a great model and something that I would like to use rather than carrying around a bulky laptop. When the technology reaches a certain point, I would indeed like to stream everything I own.
The problem with this model is that, with the exception of societies like South Korea (where there is free wifi virtually everywhere) you cannot assure that you get web access everywhere. The only solution, it seems, that would be reasonable is to build tax-funded wifi infrastructure throughout all urban areas within a sovereign state. Internet, in a sense, would be completely "free" (you're paying taxes) where ever you try to access it.
Considering the immese advantages that one requires from online access, it ought to be a right for everyone to have access to.
