Space-age indoor gardening kit

[1]In my quest for hydroponics growing options [2] for growing potentially salty tomatoes, I stumbled upon this thing that looks like it belongs on the Jetsons: an Aerogrow Aerogarden Kit [3]. Instead of hydroponics, it uses an aeroponic [4] system, where the roots dangle in moist air. It looks great for growing fresh herb plants through the winter months and things like that…and the web site says [5] it only uses the equivalent electricity of a 60 watt light bulb. I just love that futuristic-retro design too! If anyone has this, I’d love to hear about your experiences with it.
