I'd like one of these too ...
... to replace my over-the-range microwave oven (I haven't used my microwave in years since learning how unhealthy it is to eat microwaved food).
Unfortunately, from what I've learned from my research on toaster ovens, they are generally not insulated enough to even safely install on a shelf over the stove without huge space buffers on the sides and top.
Also, you wouldn't want to customize your kitchen around such an oven too much, since the new ones all have an inherent design flaw: combining electronics with heat (and lack of insulation). Purely mechanical toaster ovens can last for years, if not decades. But toaster ovens (with their notoriously poor insulation) with digital controls are pretty much guaranteed to fail within 3-5 years (if they even last THAT long) because the delicate electronics cannot withstand the heat from the oven.
