The difference was that one was a sort-of prototype that was maybe going to be on the market late 2010 or in 2011 and run some version of Windows... maybe. Ballmer handled the HP pad like it had been dipped in dogsh*t before it was handed to him.
The Apple was a finished product group that was presented professionally.
No no no, it was basically the same thing, two unknown products introduced, with HP Slate supposedly to come out in May. And even if what you say is true, do you believe that warrants the same difference in media hype that they both received. Would the HP Slate had gotten the same type of media hype that the iPad did if it was set to be released in February? Like I said, be unbiased.
