Touchscreen technology, while it has been a while for some time now, has become quite more popular this year. What with the Apple iPhone fame, companies have been introducing their own touch phones or touch laptops. But it would be long before such gadgets dominate the market so it’s best that we look for alternatives such as the Duo.

Duo is a product by Pen and Free, a Korean company. This device brings touch and table capabilities to any monitor.  It’s useful for a $44 gadget but I still don’t get how it works. I have yet to see a demo so anyone who’s got one, please show me. Tell me this is worth my attention.
