When the PC era began in the early 1980s, you’d be lucky to find a computer for under $3,000. Today, you can buy a notebook that’s hundreds of times more powerful than the original IBM PC for well under $400, but for many people around the world, even that is too much. A new generation of low-cost tablets, USB-sized computers and miniature motherboards can put an entire world of computing power in the palm of your hand for as little as $25.
More than just a machine with a cute little name, the Raspberry Pi flaunts high-performance video and graphics on a single-board computer. It can even run popular video game Quake III and play back full HD video using HDMI. Developed in the UK by the Raspberry Pi Foundation, this "system on a chip" was originally built to help teach basic computer science in school. Today, the Foundation offers two flavors of Raspberry Pi, priced at $25 or $35.
