"In October, online retailer Amazon (AMZN) debuted the Kindle, an EV-DO (evolution data optimized) e-book reader priced between $400 and $500."
I suppose "debuted" is a little wrong unless it was done so in private.
More interesting to me in the article was the comments from McGraw-Hill about their new site CourseSmart where etextbooks can be purchased. Don't get too excited. They only have a few titles available so far and they appear to be only viewable online and with a pretty hefty subscription (50% of the list price of the pbook) per title for 180 days. It could be a nice way for students to save some cash although comparable to buying a used pbook copy.
