With so few units and the high price, would it have been better for Sony to simply sell the PS3 only from an online store? Sure only the hardcores would know about it and buy it, but thats not much different from the hardcores sitting out in the cold for a week in line to buy one. Either way, the general public wont be getting their hands on them.
The only thing I could see is B&M stores would be pretty pissed, and Sony would lose all the news and hype surrounding the lines. Though with all the violence and near-riots, that might not be the kind of publicity they want.
