This is not an easy question to answer because it depends on the Bluetooth standard becoming widespread and stabilized, and currently, this is far from being the case.

In the meantime, though, the Microsoft Wireless Optical Desktop for Bluetooth is a top-range, high-performance keyboard and mouse set that works like a dream. It is ergonomic, communicates flawlessly, and plugs unobtrusively into a laptop. Add to that the fact that you can connect other Bluetooth devices to it (check which ones before buying).

So, we could say that these features are worth the rather costly price of $159, even though the future of the standard is not assured. If you want to use your phone as a modem or connect a compatible Bluetooth printer, the investment is certainly worth it. But it would be most helpful if Microsoft ensured the spread of its Bluetooth solution with more versatile, and, above all, better-designed drivers.
