Boy, this is one pointless debate. Your point is that Bluetooth is not widely accepted because of the existence of 802.11.
It's like saying the reason people don't use GPS is because of the availability of television. Of course more people use TV than GPS, but that does not mean that those usage patterns are interrelated.
If you agree that Wifi and Bluetooth are ENTIRELY DIFFERENT technologies serving ENTIRELY DIFFERENT purposes, then how, logically, does one have an impact on the acceptance of the other.
The existence of 802.11 has ABSOLUTELY NOTHING to do with the acceptance, or lack thereof, of Bluetooth. If there is greater use of wifi over bluetooth, it is because there is a greater demand for what wifi offers over what bluetooth offers, just like there is a greater demand for television programming than there is point-to-point GPS mapping assistance.
Wifi is used for ethernet connectivity. There is a great demand for ethernet connectivity today. I (and I would assume most others who use Bluetooth) do not use it for ethernet connectivity. I use it for mobility, for which it is much better suited than Wifi. Clearly, there is a greater demand on the part of the so-called "mainstream" for ethernet connectivity than there is for mobility. If I am at an airport, I pop in my Wifi CF card into the Axim and I have a speedy connection to the interrnet using the ethernet network available at the airport. If I am in my car, that Wifi CF does me no good. But if I pop in my Bluetooth CF card into my Axim and turn on my Sony Ericsson cell phone, I have access to the internet without the availability of an ethernet network.
It is simply bad advice to suggest that wifi negates the need for Bluetooth. If all you care about is connecting to an internal network over ethernet, then Bluetooth is NOT AS GOOD AN OPTION as wifi. However, if you want to maximize mobile wireless connectivity to the internet no matter where you are (your car, the beach, a Mexico City street, a hillside trail), and to maximize wireless connectivity between disparate devices (computers, handhelds, telephones, speakers, headsets, etc.), then bluetooth is, currently, your ONLY OPTION.
In other words, GET BOTH.
