Wi-Fi is great.when it works. Overall, Wi-Fi hotspots aren't universally reliable—in other words, I never know where I'm actually going to be able to get a signal. Thankfully, the cell phone carriers have been offering a solution that access-hungry users need to know about: 3G data cards.
For months, I have been praising—at the top of my lungs—the virtues of high-speed, 3G data cards from Verizon, Cingular, and Sprint. These cards go into the PC slot of your laptop and use the high-speed networks of cell carriers to give you broadband speeds anywhere there's a mobile signal. You can also use some PDA phones, such as the Treo 700, as an EVDO modem. If you live in a major urban area, you'll get about 10 times a dial-up connection. In more rural areas, you can still surf, but at slower speeds that are about three times a dial up connection. The easiest (though also the priciest) option is to just get one of the new laptops from Lenovo (the Thinkpad series) or Panasonic (the Toughbook 74 and the new W5, pictured), which have EVDO-capability built right in.
This means I no longer have to worry about whether there's Wi-Fi or not in the airport lounge where I'm trapped due to flight delays. I also don't have to spend the lousy $6.95 for one-hour's Wi-Fi network use, buy cards with codes on them, search around for a strong network, or any of the other countless little hassles and expenses that come with trying to get online with Wi-Fi. Of course, this comes at a price, but one that I don't think is exhorbitant for anytime, anywhere coverage in metropolitan areas. Right now, you can buy cards for anywhere from $50-$100 on the Verizon, Sprint, or Cingular sites (in fact, right now, Sprint is offering the Pantech Wireless PX-500 for free after a mail-in rebate). Monthly charges hover around $60 per month for unlimited usage in the United States—again, worth it if you're a frequent traveler who needs access anywhere there's a cell phone network, anytime.
