Someday, we’ll tell our grandchildren how we had to drive around town looking for a coffee shop when we needed to get online, and they’ll laugh their heads off. Every building in America has running water, electricity and ventilation; what’s the holdup on universal wireless Internet?

Novatel's MiFi, a 3G Wi-Fi router.

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.

The MiFi gets its Internet signal the same way those cellular modems do — in this case, from Verizon’s excellent 3G (high-speed) cellular data network. If you just want to do e-mail and the Web, you pay $40 a month for the service (250 megabytes of data transfer, 10 cents a megabyte above that). If you watch videos and shuttle a lot of big files, opt for the $60 plan (5 gigabytes). And if you don’t travel incessantly, the best deal may be the one-day pass: $15 for 24 hours, only when you need it. In that case, the MiFi itself costs $270.

In essence, the MiFi converts that cellular Internet signal into an umbrella of Wi-Fi coverage that up to five people can share. (The speed suffers if all five are doing heavy downloads at once, but that’s a rarity.)

Cellular wireless routers, as they’re called, have been available for years. The average person hasn’t even heard of this product category, but these routers are popular on, for example, Hollywood movie shoots. On-location cast and crew can kill their downtime online, sharing the signal from a single cellular card that’s broadcast via Wi-Fi.

Those machines, however, get no cell signal on their own; you have to supply your own cellular modem. They’re also big and metal and ugly. But the real deal-killer is that they have to be plugged into a power outlet. You can’t use one at the beach or in the woods unless you have a really, really long extension cord.

The MiFi is remarkable for its tiny size, its sleek good looks, its 30-foot range (it easily filled a large airport gate area with four-bar signal) — and the fact that it’s cordless and rechargeable.

How is this amazing? Let us count the ways.

First, you’re spared the plug-and-unplug ritual of cellular modems. You can leave the MiFi in your pocket, purse or laptop bag; whenever you fire up your laptop, netbook, Wi-Fi camera or game gadget, or wake up your iPhone or iPod Touch, you’re online.

Last week, I was stuck on a runway for two hours. As I merrily worked away online, complete with YouTube videos and file downloads, I became aware that my seatmate was sneaking glances. As I snuck counter-glances at him, I realized that he had no interest in what I was doing, but rather in the signal-strength icon on my laptop — on an airplane where there wasn’t otherwise any Wi-Fi signal. “I’m sorry,” he finally said, completely baffled, “but how are you getting a wireless signal?” He was floored when I pulled the MiFi from my pocket, its power light glowing evilly.

NUTS HISTERIA

Are Nut Bans Promoting Hysteria? Worries about nut allergies are intense in some circles. (Lars Klove for The New York Times) Every parent of a school-age child has heard the warnings about nut allergies. Some schools ban nuts entirely, while others set aside special nut-free tables. Parents are often quizzed about the ingredients and preparation methods for birthday treats they send to school. One parent told me she was asked whether a clean knife used to cut brownies had ever been used to spread peanut butter. While nut allergies are clearly a risk to some children, often the response to this health concern represents “a gross overreaction to the magnitude of the threat,” argues Dr. Nicholas A. Christakis, an internal medicine doctor and professor at Harvard Medical School, in a recent column in the British medical journal BMJ. In the column, Dr. Christakis points out that about 3.3 million Americans are allergic to nuts, and even more — 6.9 million — are allergic to seafood. But of ...
