Poppin' the lower LCD off some adhesive seems scary, but isn't too bad. No heat required!
There's a protective plastic film over the lower screen, both to protect the LCD and enable the touch action, so we feel pretty safe pushing on it.
The plastic LCD cover is threaded with a very-faintly-visible grid of dots. We didn't notice it at first, and taking a photo of it is near impossible — but it's there! We promise!
Resistive touchscreens like this one rely on contact between two layers of resistive material to register a touch. This way you can use a capacitative-touch-unfriendly stylus.
