For those of you (like me) who find yourself using different flash memory cards with a variety of devices, Atech Flash makes a nice multi-slot card reader that can be mounted internally in a PC.
This is a 6-in-1 solution that accepts Compact Flash Type I/II, Multimedia Cards, IBM Microdrives, Secure Digital Cards, Smart Media Cards, and includes a front-side USB port to boot.
This is designed to hook up to a USB port, but they also make a version that hooks up to a IEEE 1394 port for high speed transfers.
And it will work with Wintels, Macs and Linux boxes. Slick.
