If anyone here has a new Macbook Pro, I have just found a very nifty feature. I recently went to switch batteries in my MBP, and without thinking, just closed the lid (effectively putting it to sleep), flipped it over, and pulled out the battery. It was not connected to a power source, therefore it immediately shut the system off. I had a good deal of work open and unsaved, so I was pretty worried. However, after putting the new battery back in and powering the machine on, I was treated to a wonderful surprise: My screen came back up instantly, with all of my work open, and a little progress bar indicating the machine was retrieving my previously opened programs and documents from ROM. Simply amazing. Could this be a hint that instant boot is coming in Snow Leopard? Picture attached.
