Physical vs Virtual

The Raspberry Pi, a $35 credit card sized computer, is a popular choice for home automation projects. I am running few of those at home myself. But what is the true cost of these, is the advertised cost of $35 really all you spend?  Before you know it, you throw in  more bucks for a decent power…
