- I think if CF is in it should be external, particularly if ethernet won't be on-board. I don't like using USB as my "network" connection. It's okay for peripherals, but for actual networking I vastly prefer ethernet over USB and some kludge to make it look like a NIC, that only works on the one computer it's running on. Ikky. I'd much rather plug into my network like a real computer, when I'm on the wire.
- I like the micro-SD idea for the OS, with miminum internal flash, and I really like stampsm's idea of using a "break-out" ribbon cable for development. I'd still like to keep at least one, and without CF more than one, full-sized SD slot.
- Biometrics are a nice-to-have, but not necessary, imho. I'd rather type in a password and have Raid-on-SD than have a bio scanner, or even a camera.
