Rumor sites believe that apple’s upcoming Tablet “iSlate” would carry a front facing video camera as recently described in the Wall Street Journal:

This person said Apple has experimented with the ability … for the gadget to automatically recognize individuals via a built-in camera.

While the presence of a front facing camera could allow for this novel use of facial recognition, it would also open up the possibility for video conferencing, which has been a long requested feature for the iPhone. Apple already supports video conferencing with their Mac OS X iChat software, so the ability to tie in video conferencing with their existing technology would be trivial.
