Some electronics gear has three feet. I've owned some of it. It always seemed unstable to me - if I leaned on a corner by accident, it would just about tip over. Having said that, if the product in question is the proper shape, three would work just fine. A floor standing speaker that is quite narrow but very deep comes to mind (think audio physic) Two spikes in front, one in back.

Why is it that the majority of audio equipment comes with four feet rather than just three? It seems that only having three would provide a more solid foundation that would better resist vibration and rocking. Speakers come to mind as a component that might really benefit if it was part of the original design.
Any thoughts? Are there companies that do this that I have not seen?
