I remember a visit to Redmond back in 05 where I saw a large number of Microsoft employees using old "tablet" form laptop computers (those where you'd rotate the screen over the keyboard to use a pen-like pointer). It looked ridiculous, except for being a clever/good use for Microsoft OneNote at the time. There's no way those tablets can be compared to today's tablets, which are a fraction of cost, weight or thickness. I'll also say that while battery life did make a difference, the actual way you interact with the OS was one of the mian reasons for the tablet tipping point. The clunky mouse pointer (controlled via pen) of yesteryear pales in comparison to what we use today. The fact that the bar for interaction is so high now makes people crave a tablet experience, even if only for experiencing the novelty of touching interfaces they used to only be able to point to, with their full hands.
