Sure, you can turn it off or do what I do and choose not to carry a phone. The bigger issue is that such a silly and intrusive use of technology is generally seen as positive and desirable nowadays.
If you are looking at a Mac Pro in the store and decide that the real product in front of you with the information sheet on the product's iPad display thing isn't sufficient, and you want to look up more information about it on your phone for some reason, it isn't that hard to search Google for Mac Pro or go the the Apple web site, etc. But that level of technological wizardry isn't good enough! Your phone should already be displaying information about the Mac Pro when you're in front of it, subtly encouraging you to consume more products!
