Sneaking by just in time to make its delayed end of February launch window [1], the $35 computing wonder known as the Raspberry Pi [2] is on sale at long last, Yahoo! News reports. The teensy machines went up for an eBay pre-sale auction [3] for charity in January, and fetched as much as $3,000 for a single unit. Now curious members of the public with not-so-deep pockets can get in on the fun—if they can squeeze in an order on the overwhelmed sales sites that is. Due to overwhelming demand, the two sites [4] retailing the micro-computers have both been overloaded, and many would-be Raspberry Pi owners have reported that orders aren’t going through. While a $25 version of the tiny device will go on sale later, the first Raspberry Pi round is the $35 “Model B.” What does that extra $10 net you on such a tiny, bare-bones computer?
