I'm going to have to see one in person first.
The updates are awesome, and with apple releasing GarageBand and iMovie I think it shows that they are starting to make the iPad into a more content creation oriented device, so the dual core processor would be nice.
I really like the cover idea though, I am always taking my iPad case on and off because I like the feel of just metal and glass, but sometimes I need to prop it up to type on, so I think that cover fits the bill for me.
As for the cameras, they are cool but I would like to see what the photo resolution of the back facing camera is.
So I may upgrade, it depends how my current iPad will perform with GarageBand.
