That's rather thin sales, considering the fact that the EU alone has over 500 million people. And it took Sony 8 months to sell 500k ereaders to that enormous mass. I would like to follow the practices of other blogs and talk about how great this sales figure is, but to be honest it sucks. When you put it in perspective it is almost embarrassing to Sony.
You almost have to ask why they're still in this market, don't you? The answer to that is simple: they don't know when to quit. Sony is like that guy trapped in a hole. All he knows to do is keep digging until he's not in the hole anymore, rather than climbing out.
