"The most exciting area of computing has always been micro technology. Making what is large today into smaller, more usable forms has driven many advances in the computer industry. In the last fifteen years, computers have moved from the desktop to the laptop and notebook computers have become the computer of choice for most people. However, as small as they have become, notebook computers are still not small enough for many specialized uses and users. I have always been fascinated by handheld sized computers. Not necessarily the handhelds that reduce the functionality of a computer to a basic subset, but handhelds that have the full capability of the current, full-sized versions. I still own, and occasionally use, an IBM PC110 and Toshiba Libretto 70. For those who do not know, the IBM PC110 was the worlds smallest 486 computer (the size of a paperback book) and the Toshiba Libretto was the smallest Pentium 1 computer (the size of a VHS video cassette). Both were complete computers with color screens, keyboards, mouse pointer, docking stations, etc. running full versions of Windows. Now a revolutionary handheld, from San Francisco-based OQO, brings the current level of computing power into the worlds smallest Windows XP computer. "
