I just read an article that 44 Microsoft if opening 44 new stores in their revamped format this year.
Techno Buffalo had done a nice video walk through that features a few things of interest in thinking about multichannel and the store of the future:
Merchandising up front - there is a nice little display of the Xbox right up front which is linked to a billboard out in the mall drawing people in. Generally in Sprint stores the key ofcal point on entry is someone standing behind a check in desk.
Digital Screens - the slate and other digital wall screens are constantly changing the message within the stores and keeping information fresh
Endless Aisle - in the back of there store there is an interactive kiosk where you can select from a bunch of software which is then given a license key and then printed in the back for you. There is no need for stores to carry all this software.
Guru Bar - not a genius bar but a place where you can set an appointment to get your Microsoft questiosn answered.
Check out the video and / or visit a tore near you to see what they are doing.
