There is a way for you to touch-enable your existing PC without having to throw the whole thing out.
You can replace your existing monitor with a touchscreen panel. And it won’t be a big financial burden.
You take a look at Acer’s T231H 23-inch LCD panel. Not only do you get a really nice 1920 x 1080 full-HD screen, but you’re adding touchscreen support to an existing system for around $320.
The Acer T231H is a great touchscreen, but there is one limitation. The screen has a bezel around it, and this makes it tricky to get to the edge of the screen to make use of Windows 8’s edge gestures.
A solution to this problem is to use your graphics card driver to underscan the display slightly to bring the edges in a little. You’ll lose a few pixels at the edge, but chances are you won’t notice it. Both AMD and NVIDIA offer an underscan–overscan ability in their drivers, so it’s quite easy to do.
