The Surface Pro starts at $899 for the 64-GB model. The detachable keyboard/screen cover runs $120 for the Touch Cover or $130 for the Type Cover. The total price for a Surface Pro -- which isn't a fully functional laptop without a physical keyboard -- is north of $1,000. Since the device can (theoretically) replace both a tablet and laptop, its price tag may seem reasonable. But do consider the Surface Pro's shortcomings -- particularly its battery life and weight -- before you buy one. Indeed, you may be happier with a separate tablet and laptop instead.
