As widely expected, Apple has just updated the official Apple Store app to version 1.3 including custom configure options for Macs and the ability to get support quickly inside an Apple retail store. Contrarily to previous speculation, the app seems to be US-exclusive and doesn’t include an iPad universal version for now. With the new configure options, users are now able to build and order the Mac they want by selecting different RAM configurations, hard drives, displays and more — just like on the Apple Online Store. As for in-store support, the screenshot below shows you can access Mac OS X Tips and Tricks and workshop schedules, see how many customers are in line in front of you, and check out the next opening at the Genius Bar.
