With the release of the iPad, the street price of Sony's eReader has fallen off a cliff, dropping by more than 50%. Check it out:

For those of you newly interested in DSLR, check out Amazon's price drops for the Canon EOS Rebel XSi. After a year of dropping the price, it finally seems to have found a floor -- which usually means it's a good time to buy.

This week the Nintendo Wii jumped back to the top of the charts after it's recent price decline to $199. You can see that it had been declining in popularity slowly ever since the holidays. It remains to be seen if this is a temporary bump or a real sustained trend.

XBox 360's HD-DVD player is acting as a bellwether for HD-DVD's recent troubles. Amazon.com dropped their price for the player by a third, and Buy.com followed suite.
