It does feel like it... But don't feel scared of open it. It's not going to break. The slider mechanizm was made for it to slide up and down. It's a lot better than touching the screen all the time. (note) for the slider to be broke, you would have to do it. (The hardware of the phone is also coverd by insurance) cheers!
Opening the slider answers a call... And there is also a patch in preware that ends a call, when you close the slider.
Thanks. I already knew that. I saw Jack Bauer on "24" worked his Palm Pre that way. After that I found and installed the "close slider to end call" patch. Although I am still looking for a patch that allowed him to have a decent phone conversation in the middle of a gun battle.
