The Surface Pro will compete with those devices and others. But, based on how good that Type Cover is and how good the Surface Pro's screen feels -- not to mention its small size -- the Surface Pro seems well-positioned to rise to the top of the pack. From the moment the Surface was announced, the real killer feature was the Type Cover. To me, the success or failure of the Surface hinges on the ability of that cover to be comfortable and productive. And I think it is. It also draws power from the tablet, never needs recharging, and has a grip strong enough to hold the whole Surface tablet from the cover alone.
Can a tablet comfortably be your full PC? So far, when it comes to my limited time with Surface Pro, the answer seems to be yes. And that could, in the long run, be the most impactful development in PCs in years.
