Agere is starting production of a "mobile content server" called the BluOnyx.

The 6-15mm thick rectangular box sports Bluetooth, a mini-USB port and an SD slot to increase capacity.

The units won't be available until April 2007 but like MSI's similar box, I'm struggling to see an audience for this kind of a device.

Agere hypes the ability to stream content to mobiles phones. It says the unit is "for the YouTube generation" but surely the YouTube generation will be watching YouTube...

Serious users may be better off spending a little more on a proper network attached storage device, like the HP Media Vault we reviewed last month which has a decent sized hard disk and can read and write at 50Mbits/sec, much faster than Bluetooth's theoretical maximum of 3Mbits/sec - if more than one person tries streaming from this "mobile content server" the thing may grind to a halt.

I suspect the real inspiration behind these hard disks is the ever thinning margins and Bluetooth, SD and flashly light add-ons may be the only way to make a profit. Prices range from £50 for a 1GB flash based unit scaling up to £130 for the 40GB 1.8in hard disk device.
