Egg cookers....
If I had a larger kitchen I'd get one of those, even though surely not in the list of "must have" for me.
I used to have a weird and ugly modern one that was cow shaped (what cows have to with eggs then??? LOL), it was given to me as a birthday gift, it was kind of useful in certain occasions as it allowed me to follow something else meanwhile.
Needless to say that it didn't find it's use daily and often it was really less time and bother to take out a pan than take out the cooker, measure water plug and set up the thing, that is why mine ended up on sale, but if I had a larger kitchen I'd have kept it, having it ready on the counter makes it worth it for me...
I do not have eggs for breakfast, actually I always skip breakfast... but I think that for those who eats eggs often and have to do something else meanwhile it is an help, not needed as a toaster, but sure a little further help.
I think that while the thing cooks automatically one could get prepared for the morning without the risk of overcook them...
