iPad disappointments

Gauging from the rampant speculation, there would most likely be a number of people who think today's announcement didn't live up to the hype. A game changer does not come along very often so I didn't expect way too much, but came away with a few disappointments

• No ability to make calls from the 3G device i.e. it will not be attached to a phone number. You can still make calls over wi-fi but what's new about that?
• User interface seems almost like the ipod touch, so what's new about that?
• No camera (or is there one?). Very sad if there isn't one as this would have been ideal for video chats
• Can't multi task? I think it should be able to especially since it's competition is not phones but netbooks. I need to follow up on this
