If you're looking for an Apple Watch (and you're shopping old-school, brick-and-mortar style), you won't be able casually dip into an Apple store and get some new tech-laden wrist candy. Not so fast: According to training documents seen at MacRumors, there will be no walk-in sales, at least to begin with. Customers will have to make an online reservation ahead of getting to buy it, supporting rumors that there may indeed be supply concerns. Those who do make a reservation will then then get to try on a watch and have a play sometime between the April 10th pre-sale launch and the April 24th on-sale date. It won't be this way forever, though: According to the leak, Apple will likely offer walk-in sales at a later date.
