Bug the neighbors with an MP3 doorbell

This ringtone business has gone too far. It's one thing for everyone to have a "signature" tune for the cell phone, and we can even live with customized land lines. But doorbells? Enough already.

What used to be a DIY thing has now gone mass market with the "USB Doorbell," a device that lets you play any MP3 file instead of the usual chime for up to 30 seconds, according to Everything USB--which, depending on your taste in music, could easily seem like an eternity to an unsuspecting visitor. For just $100, you too can be the obnoxious neighbor we're used to seeing only on TV.
