I think the public atl-large has gotten the message that WiFi is all the rage. It seems that everybody is buying a device (or devices) that are WiFi-capable. No one wants to stay tethered to one place anymore just to surf the web.
This story in the New York Times discusses the proliferation of WiFi routers and adapters being manufactured for laptops and desktops, and the fact that most of them are being built under the 802.11n spec, which probably won't be ratified by the IEEE until sometime in 2008.
The thought here is that should consumers, as well as enterprise customers, spend the money to purchase these "Draft N" products before the spec is made official? What if a serious glitch is discovered or, better yet, a new spec is developed that will make 802.11n obsolete? What happens then?
Of course, if these Draft N products are the best in existence and they promise to make your WiFi experiences productive ones, then there really is no other alternative. WiFi is still an evolving technology, and it will take several more years of research and development before a spec comes along that will make things "perfect", if there is such a thing. Until then, we'll have to make do with what is currently available, and see where it will take us.
