It's probably overcrowded during certain days like weekends or something. During weekdays, it's more milder.So many people in this thread are complaining about their current store always being over-crowded, or the next available Genius Bar appointment being so far in the future (because the store doesn't have capacity to meet the current demand).
I think even without any new products, continuing to open new (and expand existing) stores will still be a benefit to customers in crowded markets. Which seems to be the majority of them, listening to folks post in threads like this here on MR...
Everyone has different experience and perspective. Can't blame them for that.
Those current hardwares may or may not benefit customers. If they already seen those products...well...that's that..they wouldn't come back unless they need accessories, buy products, plug their files to those hardwares to work, or just browsing with those.
