Amazon is sending book-loving gadget fans into a frenzy with another round of domain name buys. It registered KindleScribe and KindleScribes.com to go along with the KindleAir and KindleSocialNetwork addresses it picked up earlier this month. All that's left to do is speculate wildly on what they could represent (Thin and light e-reader? Tablet-style touchscreen? Kindle that comes pre-loaded with the Social Network?) and hope the new devices come packing Jeff's newly patented mobile airbags.
