Having used a standard toaster (also KitchenAid) for years, I thought having oven space too was important in my next purhcase.  However, I realize that I simply "toast" most of the time, so some of the features don't get much use.  And with that much space inside, just "toasting" can take an incredibly long amount of time.
However, the few times I've used the other options, I've been completely satisfied.  A more speedy bake than in my standard oven, and a pretty quick preheat.    Not to mention, it looks pretty!  : )
One miss element:  No way to turn off the timer except by running it out.
