As has been mentioned some weeks ago, it's pretty easy to record GPS information and, later, incorporate it into photos taken on a non-GPS-enabled camera.
Unfortunately, the current camera lineup doesn't really please people that would like to geotag their shots. Neither the, because of the high price-value ratio or high image quality (IQ), most popular point-and-shoot (P&S) or DSLR (including mirrorless [aka DEVIL] or some lower-end [Sony] SLT) cameras have built-in GPS modules.
Some examples of the current, most popular cameras lacking any GPS support:
P&S-style "luxury" fixed-lens camera
Fuji X100
