Very interesting, but not alot of information there. For example, where do the big image files download to? Is there a gig of memory in that box to hold files? Is that a stick pc plugged in the side?
Nice. Low power consumption. Low cost hardware. The RPi can write to an SD card (slowly) or an external USB HD (a bit faster). Reliability is not passed on - it could be very good or very bad or anywhere in between.
I'd say it looks pretty neat for US$139...to buy a Raspberri Pi and touchscreen locally would cost more than that, and then the software is value added
