Ever sit down at your PC and think: You know what this thing needs? Diamonds! If so, British retailer Fabstuff has your number. For $25,700, the company offers "the world's most expensive computer mouse," a wireless gadget studded with 59 diamonds, which can be arranged in a variety of designs -- including the buyer's initials. The mouse, which is made-to-order by a Swiss firm, also has panels of 18-karat white or yellow gold, making it the "perfect gift for a 50th wedding anniversary," says Fabstuff.
The mouse might class up your desk, but it won't do much for your computing power. Fabstuff notes that the device is wireless, but that's hardly cutting edge; 76 percent of mice sold in the U.S. last year were wireless, according to researcher NPD Group. There are many more advanced models available, says Chris Harrison, a Ph.D. candidate at Carnegie Mellon University who specializes in mobile-interaction technology, adding that he wouldn't pay more than $100 for a mouse. (Fabstuff says it doesn't advertise the device as technologically advanced, and the price reflects the cost of materials.) But when it comes to the gadget's high-end casing, all that glitters isn't gold -- or diamond, for that matter: The mouse's trim is made of plastic.
