Some people like a perfectly clear, clean, sleek countertop. Others want to have frequently-used tools near to hand. Some of us don't have the luxury of a decision based on aesthetics or function; we simply don't have room in the cupboards for large appliances, or we can't afford the counterspace for a blender and mixer.
I don't have a great abundance of countertop space, but it is a rather deep space. So I keep my KitchenAid tucked in a corner, and the electric kettle, burr grinder, tea maker, and toaster out on the other side. There's also a small microwave on another side of the kitchen. I simply can't imagine swinging these out every time I needed them, even though they do clutter up the counter.
What about you?
