Well at least some stores are banning the popular social networking sites from the instore computers. While alot can be said including that its an evil move by a big corporation. Although it is since been found out that Apple is not doing this by a policy and it appears only a handful of stores are operating the policy.
I personally think that Apple will enact such a policy across all stores soon, they want to stay profitable after all and time is money. The time spent dealing with questions and people who a clearly not there to buy only to check their gmail account has to stop. Apple has a massive retail presence based on quality of staff, if they are to keep the quality of staff high and thus maintain this appearance through the oncoming storm, they have to draw the line at some point.
