Garmin have announced the "nüvifone", which is a sort of iPhone for sailors, with a 3.5-inch touchscreen GPS navigation and 3G mobile phone in a handheld gadget. It has a camera which will tag images with the latitude and longitude of where the photo was taken (but not what direction the camera was pointing). This can then be interfaced to Google’s Panoramio photo search. There are not a lot of specifications released about the unit, but I expect it will be much thicker than the iPod Touch (which is so slim I found it hard to hold). Also I expect we will see a lot more gadgets of this sort of device.
