Hi Cindy,
The issue is not so much a specific techology in terms of how we think of it, but rather a feature... their "one-click purchase/shopping" thing, their trying to copyright it so no other e-commerce sites can imitate it. Go to slashdot.org, that got all the scoop & the reasons why folks are so fired up over this. Also see http://noamazon.com too.
