A number of readers have noted the action by the U.S. Mint to outlaw the melting down or bulk export of coins. This has come about because the value of the precious metals contained in coins now exceeds their face value. The Mint would rather not have to replace pennies (at a cost of 1.73 cents per) or nickels (at 8.74 cents). The expectation is that Congress will mandate new compositions for some U.S. coins in 2007.

Iddo Genuth writes "After unveiling their upcoming hybrid hard drive, Samsung — along with a number of other manufacturers — is planning to begin shipping solid-state drives during 2007. Unlike the upcoming hybrids, solid-state drives should work with windows XP as well as Vista." The drives will be introduced in 1.8- and 2.5-inch form factors for notebooks. While streaming performance can't equal that of hard disks, Samsung claims that random-access performance is more important and that (e.g.) Vista users would see a 4x speedup in many key operations. Pricing was not announced.
