Sonnet has begun selling a new device for ExpressCard slots, the 21-in-1 Multimedia Memory Card Reader and Writer. Unlike a previous ExpressCard device, the R&W can also copy to memory cards, and does so without increasing in size; it fits flush with a notebook's body for travel. The 21 supported formats are divided between SD, xD, MMC and Memory Stick types, and include the likes of SDHC, microSD and Memory Stick Micro. Maximum transfer speed is 480Mbps.

The card costs $30, and fits into both ExpressCard/34 and 54 slots. PC users require a computer with Windows Vista or XP Service Pack 2; Mac users must have a MacBook Pro, loaded with Mac OS X 10.4 or later.
