I never understand how Apple allows its stores to remain so slow (iTunes Music, Mac App Store, iOS App Store). I'm trying to give them money. If it takes 30 seconds to search and navigate to the product I'm vaguely interested in, with a multi-second pause for each request to complete, I'll give up and not spend the money.
