Sony is going to have to do a
little bit more than land a quasi-exclusive deal with Murdoch to "win the war."
I do think the Sony hardware is pretty good, but the Kindle hardware is generally good enough (and priced competitively now) to make that moot. If B&N gets its act together quickly, same goes for them. Considering that Amazon and B&N have never made hardware like this, and Sony has a long track record making portable devices, I'm not sure that an extensive resume will make a big difference.
Unfortunately it's extremely difficult to tell what anyone's standings are, since no one is releasing device sales figures. Anyone up for a little corporate espionage?
