Previously the store update was delayed from its original launch date so Sony can patch up some of the issues that other countries that had the new store already were having.
Sony says that the store should do you more harm then good, with better filtering, organizing etc, but from the latest reports today everyone is reporting that it is running slowly. This is due to the high traffic the store is getting today. Others are talking about the store being counter productive with the ability to only see 6 listings at a time.
Let me know of your thoughts in the comments below.
