The Raspberry Pi, the crazy affordable and tiny PC, has been making waves as a great alternative for the home theater and modding crowd. Two versions are available, but the 256MB of RAM on the Model B was the source of many complaints. Luckily, the Raspberry Pi Foundation took those complaints in stride and upgraded the Model B with 512MB of RAM without increasing the price. That's right, the 512MB Raspberry Pi Model B is still only $35, and what's more is all current and outstanding orders will receive a free upgrade. Anyone who already has a Model B may be a little saddened to hear their mini PC is a little outdated, but hey, a new one isn't too far out of reach.
