Personally, I would rather a device that mixes various flavoring agents with a flavorless "base" nutrient shake to make a liquid meal replacement in any flavor I ask for. I know there is an equivalent device that uses a pallete of chemicals to produce any scent as needed by a computer simulation (for the life of me I can't remember the name of the product though, since nobody wanted to pay to smell their video games, the concept was kind of a non-starter.)

Flavor and texture are the keys to enjoyable food, with texture running a pretty distant second. Appearance and nutrition are components, but not really part of the enjoyment.
