QUOTE: However, if you think of the Surface Pro as a laptop plus tablet, things look better. You’ll have to buy a Surface Pro Type Cover for $130, putting the total starting price at $930. That’s not a bad price for a premium laptop that doubles as a tablet — in fact, it’s just about the same price as the $899 starting price for the 11-in. MacBook Air, yet gives you more display real estate, a touch screen and a pen. On the other hand, the MacBook Air’s keyboard is superior to the one on the SurfacePro Type Cover. So will this be the tablet-laptop combo that convinces you to use Windows 8 if you’re not already committed to it? No. But this machine shows that a tablet-laptop combo is not as much of a Rube Goldberg mashup as you might have imagined. It even makes sense. With each iteration, the Surface line improves. Microsoft still hasn’t quite nailed it yet. But it’s getting close. If it closes the app gap, the Surface Pro 3 could be a big winner.
