Starting rev B in earnest

First off, I started a public Trello board to track my thoughts and status. This new build will definitely break away from the idea of keeping the BOM to an absolute minimum, but I still want to maintain the idea of keeping the device size to a minimum. Towards that end, I'm adding an OLED display, 3FF smart-card slot, and am still looking for a small flash/eeprom storage chip. As an alternative to "external" storage, I might bump up the Atmel (or switch to TI) to get more storage space. Not so sure on that latter bit, as I'm more concerned about PCB dimensions than storage size.
