What is the new Apple U1 chip?
I hope this will become phenominally cheap, as I would love to see this thing used more in stores.<p>Here's a pie-in-the-sky example:  I almost always buy clothes in-person.  I want to see what I'm getting, and want to avoid the issues (discussed in other, mostly Amazon-related, posts) that come from buying stuff online.  But I often run into trouble finding the specific item (make, style, and size) on the shelf.  If each item were tagged (possibly as part of the anti-theft tag), I could be led directly to where the item is.<p>Here's a more realistic example:  I want to buy an DB9 null-modem adapter from Micro Center.  I can find out in general where it is.  But if a tag were attached to the shelf, I could be led directly to where the item should be.<p>Of course, there are tons of issues (among which cost is but one).  But it's nice to know that things like this may be possible!
