M-Systems today introduced 64MB and 128MB versions of its DiskOnKey miniature storage device. DiskOnKey is a thumb-sized device that connects to a Mac’s USB port and requires no drivers, providing a quick, portable, and convenient storage medium. Those benefits don’t come without a price, however: US$129.99 for the 64MB and $149.99 for 128MB. DiskOnKey is also available in 8MB ($49.99), 16MB ($69.99), and 32MB ($99.99) capacities.
