In a corner of the house,

stands a thing that sounds quite small.

I assure you, it's not a mouse,

but will sell you things, mouse and all.

It may sound small,

but I assure you it is not.

The biggest of, maybe, them all,

is what this person's got.

What is the thing, and who is the person?

Microsoft; Bill Gates (thinking the "corner of the house" is the state of Washington)

The title almost definately refers to Microsoft....But they dont sell hardware like mouses. They sell software. I am confused. I may need a hint.

Should we think about other companies like IBM, Apple?

[Guest]

could the answer be us? Our minds telling us to buy what we want?

This is the correct answer.

Microsoft. Bill Gates is the man. Corner of the house refers to Washington. I apologize about the confusion with the mouse, I couldn't think of any good clues.
