So Apple's potential use of self-checkout is being viewed as some amazing move? If this is the case, my local chain drugstore and supermarket are brilliant because they have had this in place for the last two years. I guess if they were employing some sort of NFC/pay-with-your-handset technology that could be considered something, but I don't see any mention of Apple doing that in this piece.
But it goes beyond that. Your local chains make you go through a pre-installed POS for payment. Square disrupted the POS by setting it free inside the store, each store rep armed with their own POS running on a smartphone. Apple, by doing this has eliminated traditionally held notions of a POS altogether.
The POS now runs inside YOUR Smartphone, inside their app. You can browse the aisles, take all the time you need and when ready, check out with out having to wait in line (which you still had to, at your local chain) and with out needing to find a store rep. That is why I called it as re-inventing the checkout experience. It didnt merely parallel the existing POS experience.
A grocery store is different. It may process anywhere from 1 to 100 items per person, some of whose prices will depend on weight. Your local chains will probably always make you go through a pre-installed POS for payment and you will probably always appreciate that fact. The volume is high enough to benefit greatly from specialized tools.
Apple can do this because it sells low-volume, predictably-priced items out of its stores. Theft is probably deterred largely by the expense of the items they sell accessories for; far fewer of their customers will want or need to steal. This is the next step for Apple. The next step for your grocery is to identify items automatically, sort and package for carryout.
They might save a small portion of their cooling costs. They won't go even by a long stretch. Keep in mind that in Luleå the summers reach 22-23 degrees Celsius easily. People are tanned and wear t-shirts, shorts and skirts up there during the summer just like anywhere else down south.
It'll be a similar design to the datacenters in Prineville, Oregon and Forest City, NC. They pull in outside air, cool it a little bit with evaporative mist, mix it with air already in the datacenter, and then send it to the servers.
The air doesn't need to be 50F, just cool enough and at a sufficient pressure to circulate heat off the servers. Sweden will work great.
But it is "Open the doors and cool the servers" cold in winter at least, so savings from cooling are sure to be substantial. Coupled with the cheap electricity in summer, and well developed infrastructure, and you can see why it was chosen.
It can be warm in Lulea, in fact it reached 30C when I was last there in June, but that was exceptional. Typically, it's sub-zero for half the year and the summer is very mild.
I'm far from a new VIMer and this scares me. While it contains a great deal of information, the noise level feels pretty high when I try to dig into it.
Sorry, couldn't resist.
