difference between ipaq-s hw6915 and hw6910

Does anybody know what exactly is the difference between
hw6915 and hw6910 ?

Thanks
Yakov

P.S.
For the record, here are their specs at hp.com:

"HP iPAQ hw6910 Mobile Messenger (FA735AA) - specifications and
warranty"

Perusing their specifications,
I can't see *any* difference.

It's camera. hw6915 has 1.3 megapixel camera. hp6910 does
not have the camera.
