I have noticed that my macbook pro's screen doesn't stay open as well as my Powerbook's. If I lean the computer forward the screen falls closed, making it impossible to use the machine while laying flat on my back (I'm lazy). I haven't gotten the chance to go into the mac store and test out their floor models. I believe that I have read some other post regarding this subject but I didn't see a thread. Apologies if there is already a thread regarding this issue but as I had previously mentioned, I'm lazy.
