Several good articles today in the Washington Post on the Wi-Fi phenom. Links to many Wi-Fi hotspot finding services. The public Wi-Fi infrastructure remains too fragmented and costly so far. Perhaps this will change over time. Of course, Wi-Fi is wonderful for in home use.
BTW, along the lines of serendipity, I met my new neighbors who are moving into their house one house away. As luck would have it they both work for Microsoft! They don't work for Microsoft Federal where I worked but still it's such a coincidence. I can't get away from Microsoft no matter how much I try!
