The release date is approaching for Microsoft's Surface Pro tablet, and reviews for the new device have started appearing. The Surface Pro differs from the Surface in that it runs a full version of Windows 8 Pro, rather than the tablet-centric Windows RT. It also has much beefier hardware specs: 4GB RAM, an Intel Core i5 CPU, and a full HD display with 10-point multitouch. Ars describes it as having the expected good performance at the expected costs of heat, noise, and battery life. "This is not an all-day machine. Surface RT probably is. But Surface Pro is not." The review praises the screen and the stylus, but points out some odd scaling issues as well. The Verge's review also mentions the scaling, and notes the strangeness of dealing with issues inherent to a Windows desktop OS — like antivirus — on a tablet. BGR looks at the big picture, calling the Surface Pro Microsoft's "declaration of war" on its hardware partners. All three reviews dwell on how the Surface Pro exists at the intersection of laptop and tablet, and doesn't quite fulfill either role. Ars says, "From the tablet perspective, Surface Pro is not acceptable. It gets too hot for a hand-held device, its battery life is woefully inadequate, and it's too thick and heavy to be comfortable to hand hold for long sessions. ... From a laptop perspective, Surface Pro falls down too. The traditional laptop has a stiff hinge to hold the screen at an angle of your choosing. ... In practice, the Surface RT and Surface Pro have a bigger footprint on my lap even than my old 15-inch MacBook Pro. And if I move a little, whomp, the screen drops off the back of my knees and folds out of sight." The Verge adds, "The real dealbreaker for me was that it's just unusable in my most common position — sitting on my couch, feet on the coffee table, with the computer on my lap."
