If Microsoft had chosen to name its book digitization and search product "Microsoft Print," it seems likely there would have been widespread accusations of copycat tactics.
But when Google renames their product "Google Book Search," nary an eyebrow is raised.
(Obligatory fair-and-balanced link: Niall Kennedy posts a Flickr photo of one of the godawful Powerpoint slides from the recent Window Live announcement, and the comments on the photo are both hilarious and damning. It is indeed true that the "culture of the deck" at MSFT is deadly.)
If it's any consolation, the Slashdot crowd did make the obligatory accusations of copycat tactics.
