The LaCie DataShare allows you to easily recycle your old SD and MicroSD cards and turn them into USB Flash Keys. I’ve used an uglier version made by a local OEM for years and it makes great use of all the data cards I have lying around. LaCie adds an additional, and mostly conceptual, differentiation between public and private data by dividing the reader in two and adding the label public and private. It looks great but it would have been nice if they had taken the concept further by allowing two public keys to mate with each other – one copying files to the other and vice versa. Otherwise a practical tool.
