Despues del bluetooth!

Reemplazará a bluetooth??, lean esto,


Wibree technology complements close range communication with Bluetooth like performance within 0-10 m range and data rate of 1 Mbps. Wibree is optimized for applications requiring extremely low power consumption, small size and low cost. Wibree is implemented either as stand-alone chip or as Bluetooth-Wibree dual-mode chip. The small devices like watches and sports sensors will be based on stand-alone chip whereas Bluetooth devices will take benefit of the dual-mode solution, extending Bluetooth device connectivity to new range of smallest devices.
This new radio technology developed by Nokia Research Center complements other local connectivity technologies, enabling smaller and less costly implementations and being easy to integrate with Bluetooth solutions.
Nokia is defining the Wibree interoperability specification together with a group of leading companies representing semiconductor manufacturers, device vendors and qualification service providers. According to the current estimate the first commercial version of the interoperability specification will be available during second quarter of 2007.

Blu Ray vs. HD-DVD

A new format battle!

DVDs have great picture quality, but the resolution of DVD video is less than the resolution of HDTVs. Blu-Ray and HD-DVD are two new types of discs that solve this problem: they look and work like DVDs, but have HD-quality video.

Sony has been partially or completely responsible for many successful standards, including the CD (with Philips) and the 3.5" floppy disk. But nobody likes when Sony tries to force their formats into an already crowded space. Sony ignored this and created Blu-Ray. It holds more data than HD-DVD, but is more expensive and complex, and can't offer combination-DVD discs. And they confusingly call the rewritable discs "BD-RE" instead of "BD-RW".
Most people don't care about the resolution of their video signals in the first place - they just want big TVs.

With Blu-Ray or HD-DVD, the disadvantages are far greater than the advantages
Why?, well.

You need to buy an expensive player, repurchase your movies, and give up cheap recording, computer playback, car playback, portable playback, and most of your Fair Use abilities.

Sony even prohibits dual-format players in the Blu-Ray license, so unless they magically change their minds to boost their competitor, you can never buy a player that works with both formats.
Most people still don't have HDTVs. HDTV programming and coverage is still incomplete and immature.

HD-DVD----Toshiba and Samsung
Blu Ray----Sony
