I've installed the solderless touch screen I purchased on eBay. It worked well and it was fun. However, its novelty wore off, and I decided to remove it. Also, I did not like the slight "haziness" that reduced the contrast little (I was being picky

).
The screen is attached to the LCD frame using a thin double sided tape. When I tried to remove the touch screen, I was careful and only applied a small force. But I ended up cracking the screen and taking the touch screen pieces at a time (ouch :cry: ). It is very fragile and easy to crack. I had to use an exact-o knife to ply off the touch screen from the LCD metal. Fortunately, I did not damage the LCD during the process. Only couple of small scratches. I think it is caused by some glass debris from the broken touch screen.
It wasn't a total loss. I ended up with the internal USB hub that came with the touch screen kit.
If you are thinking about removing the touch screen, be very very very careful. Otherwise, like me, you will end up with $100 internal USB hub with no way of getting back to touch screen.
