Sony Clié PEG-TH55
Years in use: 2004-2005
Sony took PalmOS and added WiFi, a browser, and a camera and the result was actually not bad for its time. Objectively, the camera was atrocious, but often enough, it was the camera I had with me.
My favorite photos comes from the day I had it with me in the Mapparium. In late 2005 I had it with me in a pool in Atlanta where it took its last video.
