Have you seen the Staples big red button you can press and you get a loud "That was easy"? A co-worker has one and uses it sometimes. But what about a programmable maybe 4 X 4 or 5 X 5 button grid that you can put sound bites on and play at will? Could potentially make a great office toy, given the right type of office environment, and some tact. Hasn't anyone created something like this? I'd like to buy one. (Everything I search for, like "Sound board", bring up the popular flash-based sound boards.)

Why, when a TV is turned on--even in another room--can I detect some kind of buzzing/electronic noise, that many other people around me can't detect?
