A number of people in the blogosphere are buzzing about McDonald's announcement that it will begin offering Wi-Fi technology in a number of its franchises:

Ten McDonald's in Manhattan will begin offering wireless WiFi, or 802.11b, Internet access on Wednesday, McDonald's spokeswoman Lisa Howard said.

By year's end, McDonald's will extend the access to 300 McDonald restaurants in New York City, Chicago and a yet-unannounced California town, Howard said.

Pretty cool, huh?

But it's not just McDonald's:

Besides McDonald's, Internet surfers will also be able to tote their laptops to 400 U.S. Borders book stores, hundreds of hotels and a pair of U.S. airports where WiFi access will be available by summer, companies announced Monday.

Hey, one of those airports is DFW. Thing is, you have to have a special Wi-Fi transceiver in your laptop, and apparently an ISP that supports it. Hmm...
