A few days ago I ranted about Amazon's Search Inside the Book feature.
Well, Wired beat me to the punch, but had nothing but good things to say.
As much as I dislike the corporate America-ness of Amazon, I do recognize that the new search ability is an absolute marvel, not the least because of the logistical and technological hurdles that were overcome. And how they skirt copyright law.
I still say it could stand some improvement.
