CNET.com - News - Personal Technology - IBM thinks small with 1GB hard drive for handhelds For perspective, that means the difference between a maximum of 16 high-resolution images on a 16MB CompactFlash card and almost 400 for the Microdrive. The Microdrive is also cheaper than the CompactFlash: A 128MB CompactFlash card costs about the same as--or more than--the 340MB Microdrive. The new drive also can serve as a data-exchange accessory to notebook computers, desktop computers and printers, the company said. IBM claims future applications may include wearable computers, electronic books, Global Positioning System (GPS) receivers used to guide automobile drivers, smart phones and electronic wallets.
