Windows 8 Touch Screen

I am looking at the laptop below. Is the touchscreen on Windows 8 laptops adequate for testing apps that would be bought in the store (via tablets)? I am assuming this laptop would allow me to develop and test apps, but it's not clear to me if these touch screen laptops work exactly like a tablet would.

If not, then I can buy a cheaper laptop and a cheap W8 tablet. Just looking at all my options and hoping y'all have experience with this to help in making my decision.

If you want to test your game on a tablet, you should probably buy a tablet, simply because you hold a tablet differently and controls that work well on a tablet might not work well on a laptop touchscreen.

Or get one of the new convertibles... Lenovo Yogo 13, Dell XPS 12, Surface Pro, Asus Tai Chi, etc... Currently waiting for my Lenovo Yoga to get here so I have something more than just my Surface RT to test on for touch screen...

I'd recommend getting a Surface RT as ARM-based devices have the lowest performance, so you'll be constantly aware of the baseline performance for your game.

I'm thinking of getting a secondary touch monitor too, just so I don't have to keep deploying to devices to test.
