WSJ.com - The Mossberg Solution: The Keyboard and Mouse, Now in Unplugged Bundles "The second wireless keyboard and mouse set that we tested was Microsoft's $159 Wireless Optical Desktop for Bluetooth, for Windows only. This is a more ambitious product. It aims not only to free the user from keyboard and mice cords, but also to equip your PC with Bluetooth wireless capability, so you can link it wirelessly to up to seven Bluetooth-equipped devices.
Unfortunately, I can't recommend the Microsoft Bluetooth desktop. In two separate tests, one by me and one by my assistant Katie -- in different locations with different PCs -- it not only proved useless as a Bluetooth hub, but it also failed as a keyboard."
More data suggesting MSFT is reworking its Bluetooth keyboard -- it has been off the market for more than a month, from what I can discern at
Microsoft's page for the product.
