Product review (2 stars): Excellent at first, not so much now.
I have had this range for about a month.  It boils water incredibly fast!  I have experimented with different ferrous cookware, and found that the humming reported by others is most noticeable with light-weight cookware when in the power boil mode.  Heavy-weight cookware produce very little humming.  I love the way that you can control the heat immediately, like with gas, with the added benefit that it heats up much faster than gas.  The oven is accurate and cooks well.  I have yet to use the warming drawer, but I can see using it for keeping things warm if dinner is delayed.
Updated after about 2 years of use:  I reduced my rating from 5 stars to 2 stars, and would no longer recommend this stove.  After about 18 months, the oven door suddenly refused to close completely.  There are only 2 of us in the home, and neither of us ever put any weight on the open door to cause it to "spring".  We had a GE tech out to look at it and he was not able to determine the cause or the fix.  When using the oven, we have to keep a chair propped against the door to make the door close completely.  Not good at all!  My wife has done some research on the internet and found this to be a fairly common complaint.
