Sounds like a dream come true, a WiFi cloud that you can carry with you.
As explained in this NYTimes article, "Getting online isn’t impossible, but today’s options are deeply flawed. Most of them involve sitting rooted in one spot — in the coffee shop or library, for example. (Sadly, the days when cities were blanketed by free Wi-Fi signals leaking from people’s apartments are over; they all require passwords these days.)
If you want to get online while you’re on the move, in fact, you’ve had only one option: buy one of those $60-a-month cellular modems from Verizon, Sprint, T-Mobile or AT&T. The speed isn’t exactly cable-modem speed, but it’s close enough. You can get a card-slot version, which has a nasty little antenna protuberance, or a U.S.B.-stick version, which cries out to be snapped off by a passing flight attendant’s beverage cart.
A few laptops have this cellular modem built in, which is less awkward but still drains the battery with gusto.
But imagine if you could get online anywhere you liked — in a taxi, on the beach, in a hotel with disgustingly overpriced Wi-Fi — without messing around with cellular modems. What if you had a personal Wi-Fi bubble, a private hot spot, that followed you everywhere you go?
Incredibly, there is such a thing. It’s the Novatel MiFi 2200, available from Verizon starting in mid-May ($100 with two-year contract, after rebate). It’s a little wisp of a thing, like a triple-thick credit card. It has one power button, one status light and a swappable battery that looks like the one in a cellphone. When you turn on your MiFi and wait 30 seconds, it provides a personal, portable, powerful, password-protected wireless hot spot."
Fantastic stuff, and really brings the always connected world of the cyberpunk one step closer.
