After recently visiting the USA and going to 3 Apple stores I can honestly say its about damn time Apple hurries the heck up and puts one in Adelaide.
Each store I visited was packed to the door. At least 100 people in there, lots just browsing however the main part I think we need an Apple store for was busy as hell; The Genius Bar.
For Apple products to be repaired in Adelaide you need to post it to Sydney where they inspect it and usually just send you a refurbished product back where turn around time is usually 2 weeks. 2 weeks is a long time to go without an iPhone or any other device such as a MacBook you might use for work.
I sometimes wondered perhaps their isn’t enough people in Adelaide however if there is a store in Perth surely there is enough of a demand for one in Adelaide, even if it was purely for a repairs.
In the USA each time I went into an Apple store I spent over $100, perhaps its just the white shiny lights that draw you in… but I’m sure they could make their money in Adelaide from sales.
