Not that I am an expert but looks like on the value your comparing apples to oranges. Am I missing something? Your comparing the price of a cpu only with the price of a functioning box minus a hard drive. So more realistic price might be $270-300 compared to $310. So if we balance the price the value is clearly in the Atoms favor with the first years energy savings. Still not as powerful as a i3 but a good general PC platform, MM platform, or Router/Firewall Platform.
