Go to the store that has the Surface Pro or Pro 2, and set Windows to 100% DPI, signout and back in of the computer (they'll be no password, it's on a demo account).
Once done, this is how things will look like. While I don't have have Photoshop to test it with my Surface Pro 2, personally I am using the system at 100% DPI scaling, and not the default 200%. I have good eyes.
