This will undoubtedly translate to increased sales. Now that the store is integrated into every webpage there’s a smaller barrier to entry toward making purchases. But, I’m probably the only one who misses the separation.
Apple is slapping buy buttons on big, sweeping product pages that don’t feel like your viewing them in the context of a store. Maybe that sense will change with time, but I find the site a little difficult to navigate and the design seems to assume that users will rely heavily on search to find items.
