If you have a jailbroken iPad, then you'll want to check out Quasar. As noted by Big Boss, The tweak lets you run each app in a separate window on your iPad. Each window can be resized, moved and closed just like a window on a full desktop OS. You can check out Quasar in the demo video below and then download the US$10 iPad app from the Cydia store.
