Come 2010 and no longer would you be using Bluetooth for short range file transfer. Apple, Intel, Cisco (and other major players) along with WiFi Alliance have together come with a set of standards for WiFi Direct. This will convert you Wifi gadget into a access point.

Does anyone know about the royalty situation for this stuff? Bluetooth would have been far more useful if the rights holders hadn't been so greedy in its early days.

I always thought Bluetooth was optimised for low power wireless transfer of modest amounts of data (e.g. mouse and keyboard, voice or music), not full on file transfer.

Don’t get me wrong, I would really like to say bye to Bluetooth and switch everything over to Wifi, but I don’t think Wifi is optimised for low power (the typical Bluetooth use cases) just yet. Or is it?

File transfer with bluetooth was always very slow. I use a USB thumbdrive for any kind of short range data transfer. Heck, even sending files over the internet (IM or E-Mail) seems always much more convenient than bothering with bluetooth.

the main advantage of bluetooth is not it's "direct" connectivity. It's its low power consumption. Which makes it suitable for mobile gizmos. So it wont vanish anytime soon.

Indeed. We're probably only a standard or two away from Bluetooth officially becoming the 'low power' wifi standard and a spec that allows devices to initiate connections with lower overhead and scale up to higher bandwidths if and when necessary.

Zigbee, a simplified successor to Bluetooth, has become pretty important to industrial and power grid computing; WPAN wifi was around when those standards were drafted. I don't think direct wi-fi is an automatic win.

The only thing I've ever used bluetooth for is audio; my cell phone has it, my iPod has an adaptor for it, and I have a pretty acceptable set of headphones that receive it. I'm also planning on getting a car stereo that supports it. Has file transfer every really been a use-case for bluetooth?

Getting pictures off of cellphones.

It will be interested to see how Bluetooth 3.0+HS (Bluetooth+WiFi, backed by Broadcom/CSR) and WiFi Direct (My WiFi, backed by Intel) compete with each other.

But I think Bonjour may be the biggest winner if WiFi Direct wins since, unlike Bluetooth profiles, WiFi Direct doesn't include any application layer. Bonjour will fit in the need of service discovery protocol.

i will not agree here... The battery life is incresing at a very fast pace and it wont be long when the amount of power wifi sucks will be very small when compared to the over all battery life.
