Microsoft may have a hit with power users but can't see general consumers flocking to this. If this is the future why are Windows OEMs building cheap Chromebooks? Seems to me the reason people flocked to tablets is because outside of work people were using their PC for mostly consumption purposes. The tablet was thinner, lighter, cheaper, less complex and served their basic needs. Microsoft like in the early 2000s is trying to turn the tablet into a full blown PC. Even through most people (outside of work) have gravitated away from the PC.
Microsoft's marketing is confusing too. They say Surface Pro 3 is the tablet that will replace your laptop but their marketing materials aren't comparing it to an iPad or Android tablet, but to the MacBook Air, a laptop. And if the iPad isn't suitable for productivity work, why did Microsoft release a touch version of Office for the iPad? As far as price points go they're clearly trying to compete with Apple, but do they really think this product will get Mac users to go Windows? I would imagine the percent who do would be quite small. And for non-Mac users is this product really going to entice people buying Acers or cheap Chromebooks? Go to Amazon.com and the best selling laptops excluding Macs have an average selling well under $800. I'm still trying to figure out the intended audience for this product.
