As with the likes of the Panasonic Toughbook, this appears to be something that's built from older-but-proven guts, for a very, very specific purpose (something that it doesn't appear that the writer of the Engadget article understood, given the seemingly scoffing tone about the storage space and rightful lack of unnecessary cellular networking). I suspect if it's what you're looking for, it might not be a rip-off.
