I like Kim Komando. When I wrote for the Gannett News Service (the in-house wire serviceof the nation's largest newspaper publisher)dozens of my articles appeared on the same pages as hers. Withe possible exception of The Wall Street Journal's Walt Mossberg,Kim has done more to explain technology to non-technical people than any other journalist in the general-interest media.
That said (those of you who come here frequently will note that is one of my favorite phrases), her latest column on the CNNmoney site does not shy away from listing VoIPs "drawbacks." She disses VoIP for occasional unavailability of 911 service, the difficulty of setting up extension phones, and the fact that if the service goes out, you're cut off from the world.
I don't necessarily view her comments as a "doom and gloom" scenario. In fact, I welcome them. We all know non-technical folks who get easily suckered in by the "cool" aspects of new technology. That's why objective reality checks, written in the language of the masses, are a vital element of discourse.
