I distinctly remember the BB employee saying the display for Kindle Fires are up to those reps to make them available on the kiosk.
I do not know the business model for BB per se but we all see now various manufacturer reps in the store like from Samsung, Microsoft, Kindle, Google etc. Maybe BB employess rather not deal with the devices from those companies and most give those customers the cold shoulder?
I did not make it to BB last night, I'll try this morning. I did not see the 8.9 at Staples yesterday either. That store is right next to BB. Looking forward to checking out the "killer" display and the unit being lighter than Air!
