For a long time, refrigerators were coupes: They had two doors. Then manufacturers started making French-door models, with two doors up top and a single freezer drawer below. Samsung's (005930) latest, the T9000 (which sounds like it was made by Cyberdyne Systems), is a sedan: two doors up top, two on the bottom. Behind each door is a chilling compartment, one of which can be switched from freezer to refrigerator. The T9000 also has a built-in touchscreen that can display photos, recipes, calendars, and other information. It’s part of a long and noble effort to put displays on refrigerators, even though nobody has ever really asked for that.
