In fact, the official Raspberry Pi site did confirm for a fact that the first batch of Model A samples have started to roll off the production line. Obviously, there will be some stark differences between the Raspberry Pi Model A and the Raspberry Pi Model B, where the latter will come with a couple of USB ports and 512MB RAM in addition to Ethernet support, while the Raspberry Pi Model A sports only a single USB port, carries half the amount of RAM, and loses out on the Ethernet port. Would you be willing to trade those features to save $10 in the process and use that money to buy a meal? Expect these to go on sale online from 2013 onwards.
