Re: Why !
Really, carrying around a tablet *and* a laptop may be uncomfortable for not a little percentage of users. When I travel - and even when I don't - I found my Surface Pro the ideal device. I got rid of the laptop, I also use a powerful desktop for "heavy" tasks - which again few laptops could ever match, but some self-propelled heavy models which would still lack some features (i.e. the AdobeRGB monitors...)
