Being honest & practical, it really seems pointless. Regular draining racks work well enough, even if they take time.
I also used air dry setting on dishwashers back when I had them available, and figure I'll probably do the same when I have one available again (oh, please make it soon, appliance gods!).
Although, a part of me would like this electric drying rack. If it turned up dirt cheap at Goodwill, I might get it for novelty value.
