Having owned the Original ipad(now old) since week one, and already with my share of cases, stands that won't fit the #2, I find it hard for me to justify the purchase. I'm still amazed with the one that I already own and having just upgraded to iphone4 the camera deal on the ipad 2 is not a deal breaker IMOP.
If it had a SD slot and an usb port, that might have me thinking seriously about ipad2 , but being thinner and faster and even lighter are features that won't deter my enjoyment of the "Original version". I'll just start saving up some money for #3, because if Apple stays true to form ipad 3 won't be anything like ipad 1 or ipad 2 (remember the ipod Nano & Touch ?) and soon to be iphone.
