Canon threw their hat into the WiFi camp today with their introduction of the SD430. This camera has virtually the same specs as the recently introduced SD450 but it is a half inch wider presumably due to the inclusion of WiFi.
Much like the Kodak EasyShare-one, this camera can connect to computers and printers wirelessly. Phil Askey of DPReview says that Wi-Fi in digital cameras is “a solution looking for a problem” and that when “when WiFi is enabled the small batteries in these compact cameras are likely to be sucked dry pretty quickly.”
Not sure that I feel that strongly, but currently, WiFi is an interesting curiosity at best.
