I totally agree. Some more information (for the archives):

Chips are available from http://www.analogdevices.com (iMEMS
accelerometers) and they are indeed about $10 for a 3D accelerometer.
Soldering is difficult because the device is so small. You can buy one
mounted on a little circuit board for about $35 from
http://www.sparkfun.com. Sparkfun also has bluetooth and lots of other
interesting things.
