“Does the iPad have a built-in camera? I want to do video chat and am trying to decide between an iPad and a Netbook.”
Apple did not include a camera in the iPad design. It’s possible someone may create a third party camera that connects through the dock connector at some point in the future, but for now, if having a camera is an important part of buying a tablet or Netbook, the iPad won’t provide the solution you are looking for.
On the other hand, if you simply want to transfer photos from your digital camera to your iPad, Apple sells the iPad Camera Connection Kit. The kit includes two dock connectors. One connector has a slot for connecting SD memory cards and the other supports connecting a camera via USB.
