Slotting into an ExpressCard/34 or /54 slot, the Griffin Card Reader is a cheap way to add a card reader to a laptop. It's plug-and-play and compatible with Memory Stick, SD/MMC and xD-Picture cards, as well as all of those formats' derivatives with the appropriate adapters. The card reader sits flush with the chassis, so you don't need to remove the device when you pop your laptop into its bag. We copied 100MB of image files from an SD card in just 19 seconds. If you don't like draining your camera's batteries to copy files across to a PC, this is a must.
