Small is Beautiful - VIA's VT6047 Pico-ITX
 

This board will have a 1 GHz C7 processor hard soldered into place, with up to 1 GB of memory available from 1 memory slot. This board is about the size of an Altoids tin or a deck of cards. Most of the I/O connections are handled by pin connections, which makes sense considering the small size of the unit.
