I've waited in line at my local Apple Store in the past for product launches, and I've never been able to go in and "test" the different products before. Employees walk down the line and ask you what model you want, and then you get it once it goes on sale. That being said, they MIGHT do it the way you're talking about this year simply for the fact that we can only imagine what they feel like. They have to decide which is less painful, forcing those in line to pick a model and then deal with an unbelievable amount of buyer's remorse over the coming days from people wanting to go up/down a size. Or do they let us decide what we want after playing with them for a few minutes once the doors open, but have all these stragglers who can't make up their minds holding up the line. All I know is, I'm so glad I'm not in that positionI think this will be the first time I don't preorder a phone online. Going to have to go into the store on the 19th to play with both sizes of the iPhone 6. Can't make up my mind.
