I can't wait until iOS 4.2 comes out in November. This review on Gizmodo makes it sound like it'll be a real upgrade for my iPad. The review covers features such as multitasking, folders, wireless printing, and Game Center. The biggest surprise of the review is that the orientation lock button will be onscreen and the current physical button will be a mute button, as on the iPhone. And you'll be able to control brightness from the taskbar.
