If you've ever toyed with the idea of starting a DIY-computing project, chances are you will have considered (or bought) the Raspberry Pi. You're not alone: more than five million of the boards have now been sold. It's prompted companies like Intel and Imagination to try to match their features, while devices like the $9 CHIP are hoping to outdo them on price. With so many competitors snapping at its heels, the Raspberry Pi Foundation has decided to take action. It announced today that it's cutting the cost of its former flagship board by reducing the Model B+ to $25/£16.
