The "Fit PC Slim" is one option that I'm currently looking at, the other would be with a CF configuration instead of the 2.5" HDD slot, but the price points would also be lower (thinking somewhere around $200 with wifi and a small CF, larger CF/HDD/SDD obviously adding more costs). Comparable specs in terms of processors/etc as FitPC (based around the same processor and chipset). Big advantge to this hardware would be that it has a second MiniPCI slot, so if you wanted to add more hardware that's a pretty good expansion option.

I think the external battery pack is a better idea than trying to intergrate it into the device; that way lots of options for size/capacity/etc are available and taken care of.

We all know that GA loves his OMAPs, and I'm in no way saying that the Beagle board and OMAP3 systems aren't awesome, but I just can't see them being ready for this sort of application right now, both from a development point of view and from a cost point of view.

For the record as far as power consumption goes the x86 Geode equipment is quite conservative; the big difference between it and the OMAP/ARMs is the sleep/low power modes which in this scenario I don't see as a big factor.
