Microsoft's two new tablets, the Surface RT and the Surface for Windows 8 Professional, might look similar on the outside, but they're different beasts on the inside. The former is a consumer tablet with an ARM processor, the latter an enterprise-oriented slate that's really an ultrabook in disguise.
Featuring a third-generation Intel Core i5 CPU, the Surface Pro is a full-fledged Windows PC capable of running demanding desktop apps such as Adobe Photoshop. It has other business-friendly features as well, including digital ink for pen input, 1080p graphics, and a magnetic-charging connector for a stylus. It's 4 millimeters thicker than the Surface RT and 227 grams (8 ounces) heavier. No wonder Microsoft says the Surface Pro will be priced on par with high-end ultrabooks--which sounds like code for "more than $1,000." Slated to ship three months after the Surface RT launches, the Pro model probably won't arrive until January at the earliest.
