What are you gaining? The ability to resume working where you left off (so you can reboot your computer after updates and not worry about having to shut down everything). The ability to use your computer full-screen and switch to other apps also in full screen. Better management of memory and processes so that you don't have to care about Ctrl+Qing applications. These are pretty good lessons they've learned from the iPad user experience. There's no reason why a laptop shouldn't learn from the experiences of other platforms.
