Or visit one of the AT$T Phone Centers near you...

For those unfamiliar with the AT$T VideoPhone 2500:

        1. 3.3 inch (diagonal) LCD screen
        2. Fixed focal length CCD camera
        3. Built into "feature phone" (hands-free, speakerphone, memory
           dialing, etc)
        4. "Full color, motion video"
        5. Privacy shutter for lens
        6. Uses "fax modem" technology to transmit "compressed digital video"
           (CLI's CDV) at 14.4kilobits/sec
	7. $1499 MSRP each
	8. ONLY works with other VideoPhone 2500s

I believe that the CDV codec, composed of a single IIT VP chip, produces 
128 X 114 images...which is less than H.261 Q-CIF (176 x 144). The early 
PR claimed frame rate "upto 10 frames/second" which I consider to be 
total baloney.

" A whole generation of young people are demanding video technology, and I
believe that by the year 2001, visual communications will become as important
to consumers as wireless communications," Kenneth M. Bertaccini, president
of AT&T Consumer Products.  

	" Who would you like to see TONIGHT? ...You'll never look
	  at phone calls the same way again. "
