In my 20-plus years as a tech writer, I've owned or reviewed about a zillion gadgets. Some were good, many were forgettable, and a few were downright dreadful (I'm looking at you, Microsoft Spot Watch).
But a select few gadgets earned a special place in my heart, just by being insanely cool, insanely practical, or both. On this very exclusive list: the Apple iPhone, Palm V PDA, Roomba robot vacuum, TiVo DVR and, most recently, Kodak Pulse digital photo frame. It's available with two screen options: 7-inch and the newer 10-inch.
