Amazon has been purchasing a couple of domain names recently and they seem to be fond of the term Scratchpad, possibly meaning that they could be preparing a mysterious tablet. The list of domains includes AmazonScratchPad.com and a couple of other similar related terms.
There’s also a post on Fusible about the device and references to MWS, meaning that the Amazon Marketplace Web Service is also involved. Developers could already know the Scratchpad tools, which are used to test APIs. An Amazon tablet has been mentioned by the press for some time, with supporting info related to the recent Android Appstore revealed by the online retailer.
Also, Amazon’s Lab126 has been posting careers for people with Android experience, especially engineers with LCD expertise.
