Aha. This is what I am wanting to do – reserve and pickup an iPad at my local Apple store. I’m not even sure how / why I stumbled across this, but here is where you go to get to it:
It’s a link off the Notify Me page for the iPad.
Right now, unfortunately, it is not fully working – at least for Texas. It lets me choose the state of Texas, but then will not fill in anything in the drop-down where you should be able to select your desired store location. If I click the link to go to the store locator page, that works fine and shows me my nearest local store, but will not let me do anything / proceed with it.
I’ve reported this to Apple via their sales line, but so far they are just advising that their servers are slammed and to try again in a couple hours. I also asked whether you can do this reserving in the physical store nearest you and was told no you cannot, this can be done online only.
Let us know in the comments if you get different results.
UPDATE: This is working fine, just not in my Chrome browser. I switched over to Safari and got my reservation done.
