BlueTooth is a peripheral connection technology that replaces short cables that tangle
OK, fine. Actually, Bluetooth was a Viking, or is a 2.4 Ghz spread-spectrum radio communication technology based upon a set of standardised profiles...etc, but no consumer is any more interested in that than in seeing schematics of a clock radio before buying one.
While there are countless \"end user\" things that Bluetooth
does, including command dialing, virtual LAN, file transfer, and wireless audio, the \"killer app\" (based both on what I read in tech publications and my own personal experience with friends and colleagues marveling \"and you can use it to connect...anywhere?...
anywhere?) for BT connectivity seems to be mobile internet via cell phone.
True, one must have a BT-enabled cell phone from a provider that offers data services, but that\'s not an incredibly difficult thing, unless (like me) one demands CDMA coverage as well. Word on the street (I don\'t use GSM, so I can\'t speak from experience) is that T-Mo permits HTTP access without even paying for a data plan, and a large number of GSM phones are BT-enabled, even if those buying and using them don\'t know it. CDMA is catching up, slowly: Verizon will soon be offering a Motorola CDMA phone with BT that was recently approved by the FCC.
Without some kind of access provider you\'re dead in the water with either 802.11b or BT or CAT5, or Coax,
True, but BT is the most convenient way (who wants to carry a cable to connect their PDA and cell phone?) to get access from a \"provider\" that can provide access that reaches farther than the exit door at Starbucks.
