The Xiao which came on the japanese Market about one Year before the I-Zone is clearly a
Toy camera for children whereas the I-Zone is marketed mainly as a gadget for adolescents
and young adults.
The Xiao runs on one single AA-Cell, which is only used for the flash.
There are no controls on the Xiao besides the On-Off switch and the shutter button.
It can only be used for flash closeup shots at a distance of 80 cm = 30 "
Any difference in distance leads to over- or underexposure.
The I-Zone uses two AA-cells and has a selector for indoor/close-up and bright / cloudy outdoor shots.
Th additional opening next to the lens suggests that the i-zone has some sort of exposure control.
The I-Zone uses two stainless steel rollers to develop the film whereas the Xiao uses two plastic bars.
