You can take it out of full-screen and you have the normal windows max/min/etc buttons so you don't have to push it fullscreen.
With the Chrome flash client (you can choose which flash to use in the config) it is noticeably faster and a godsend, really, but if you're on Chrome or one of the Comodo variants, you'll see about the same flash performance, just less overhead.
