Mobile OSX 4.0 is bringing multitasking to the iPhone. I think it's a safe assumption the iPad will get the same brand of multitasking soon (next week?), not least because they share apps.
Unfortunately the 4.0 software update isn't planned to be released for the iPad until the Fall. Which is frustrating to say the least as I would rather have multitasking on the iPad than the iPhone.
