A few days ago a video surfaced of one YouTube user comparing the abilities of Apple’s Siri and Microsoft’s Tellme software. With Siri found on the new iPhone 4S and Tellme being part of Windows Phone 7, it was really only a matter of time before the two were compared head-to-head.

Let me start off by saying that voice control is nothing new. Apple didn’t invent the technology. What makes Siri different is how popular it has become. It is not limited to only phone related functions, but can pull valuable information from the web too. For a worthy contender to match its capabilities will take some serious horsepower.
