I wish the microwave would let you enter a precise time (say 10 seconds) rather than 15 second increments.  sometimes i have things to defrost (for example, butter or a slice of bread) that only need 8-10 seconds, but because 15 seconds is the shortest amount of time allowed, i need to stand there and wait and stop it at the time i desire, rather than let it overheat or melt.  Very inconvenient.  Plus it takes way too long to preheat the oven.  over 10 minutes.  I thought that fast pre-heating was one of the benefits of an electric over.  :(  That said, the other features are not all that useful.  i still don't understand the whole "Advantium" thing.  I'll probably never use it.  kind of a waste of money just to get a wall oven and built in microwave.
