I saw this article, which says the Asus device could be 'revolutionary.'

Personally, I think it was a bit syrupy. In other words, someone in Asus's PR department did a good job. That being said, I can totally see the value. If I could get tablet functionality with one device, I'd be very intrigued. Battery life would likely be a concern, unless they're two separate power sources...

Now... I thought Asus introduced something like this years ago? (I remember seeing a product intro video with the CEO of Asus mocking Steve Jobs, which would indicate that it was before his death.)
