i soppose that Airport tech is much more efficent than that of bluetooth

cause
bluetooth works on        Airport works on
.Infrarad rays               .Radiowaves
.1 mbps data transfer        . 11mbps data trans
.range 10 meter              . 150 feets

well these r just few reasons

Hi, Sudeep.

The effect of Apple's AirPort on the general wireless LAN market will likely be limited by its penetration.  Currently, Apple users account for about 5% of the total computer market share, so the chance of AirPort becoming a huge player in the WLAN market is painfully small.

What's more, many Apple laptops may now (or soon will) use Cisco WLAN cards; beta drivers are currently being tested and the last I heard were working nearly flawlessly.  This has the net effect of reducing AirPort's market share further by competing directly with it.

PCs can associate with an AirPort device, so those users loyal to AirPort are able to connect any PCs to their WLAN without significant problems.  I am not certain if an AirPort card will associate with a "mainstream" AP such as LinkSys or Cisco, but since AirPort is 802.11b-compliant (and Wi-fi certified), I wouldn't think there is a problem.

Will it be helpful to wireless awareness?  I think that any new WLAN device (and the subsequent marketing blitz) will aid in awareness.  Market share, in my opinion, has little to do with awareness, though it may impact the way a device or technology is perceived.  (For example, many die-hard PC users believe Macintosh computers are garbage, not because they know it to be true through comparison, rather the conclusion is reached only after citing their small market share!)

In addition, I'd like to clear up an apparent misconception regarding your review of Bluetooth (BT).  BT technology is not an IR technology, rather, it is a spread spectrum technology, just like 802.11b and the AirPort.  The major difference between 802.11b and BT is the *way* the spectrum is spread.  

BT uses *frequency hopping*--intermittently jumping among frequencies, whereas 802.11b uses *direct sequencing,* widening the bandwidth of transmission by impressing a "chipping code" onto the signal.

I hope this fully answers your question.
