Elecom offers a MicroSD MR-SMC03 card reader that's nearly as small. The tiny, $13 device lets you insert your own MicroSD card and read it on any PC.

Both the iDisk Diamond and the Elecom MR-SMC03 are literally small enough to swallow, which is too small, in my book. If you drop it, it's like searching for a contact lens. Fortunately, both have places to attach a strap, which secures the gadget but triples the bulk.

Too cheap

Cheap is good, right? Is it possible for gadgets to be too cheap? Can phones be cheaper than free? We're about to find out.

Wal-Mart is selling a range of phones at absurdly low prices starting tomorrow. Among them are three BlackBerry phones that Wal-Mart will pay you $100 to take out of the store (as long as you leave after signing a two-year wireless contract). The way they market the phones is that anyone who buys one gets a $100 Wal-Mart gift card, and the price for each BlackBerry is zero. But let's be clear. The price for smart phones has now dropped to $100 below zero.
