Evidentally you're not aware of the requirements some users have for connectivity.
In order to remotely connect to my desktop at work, and complete necessary tasks I require the full functionality of a laptop. A smartphone will not do. Ditto for school assignments.
You cannot get WiFi everywhere.
And I am aware of the expense and technical glitches associated with EVDO and MIFI. With a monthly communcations bill over $300 for my various devices and subscription services, I'm not looking to add to that expense.
I just think it's fantastical for people to keep talking about "Internet everywhere, all the time" when that is clearly not the case unless one is willing to resort to exotic, expensive (sometimes unreliable) work-arounds.
When that fabled era arrives I will welcome it with open arms, but it's not here yet.
then thats when you get a netbook. it is light, small, cheap, and has enough room to have certain programs. but if you prefer just living in the cloud, you can find a service for anything online. Including a word processor.
there aren't many glitches with evdo and mifi. EVDO essentially runs off of 3G, soon 4G and depending on the carrier you use, your connection will be awesome, or not some awesome (possibly bumped to Edge)
and you're bill isn't really common for most people. Most people pay probably 100 dollars for all the fixings. Hell, tack it on to your cell bill, and a normal person is paying...what? $120?
Not to mention, all the open wifi spots from peoples home connection. Where I live, I can walk a short ways, and there are two open connections i can tack on to if I want. And if I don't have internet in my home, I do go piggyback.
Internet everywhere isn't far off for anyone. Eventually (if they havent already) they will simply build 3G/4G into computers big and small, and if you want, just activate it. With mifi, it is simply putting the mifi card in your pocket and letting it do it's work.
Not to mention with things like the iPhone, if you are willing, you can do anything you want on it. People have been checking and writing email forever on their phones, and now they can do all types of new shit.
