I have relatively few outlets, (House was built in 1968) and I don't see the point either - you keep everything unplugged until you have to use it. I typically keep the rice cooker, crockpot, and all of the other "occasional use" appliances in the cupboard anyway. The only appliances that I actually have in a fixed spot are the microwave, toaster, and blender. Three outlets in three different spots, no problem.

That's what I am thinking while looking at my seemingly cramped kitchen with by comparison massive 24 inch deep countertops with only 4 outlets (5 if you count the one hidden behind the refrigerator). Much more than 18 inches apart. It boggles my mind to have that many outlets.
