Ofcourse, multi-tasking should have been there. And it will get in for sure (if not officially, then via unofficial means). USB for what ? You already get enough storage onboard and if its for an external keyboard, then that is covered too.
Yes, OOTB it is crippled. The iPad OS is unfinished yet. But it still has a lot of potential (wait for 4.0

) Also, with the $499 price-point, it makes it much more desirable, atleast to me.
Oh and btw, I am not interested in the 3G model. I can setup tethering on my iPhone and convert it into a WiFi router. After that if I ever want to use net on iPad on the move, I will connect to that WiFi router
