We've recently seen two of the biggest tech giants, Apple and Amazon, trying to do just that.These competing visions -- Apple's iPhone versus Amazon's Echo if you like -- also say a lot about the strengths and weaknesses of those companies, and how they see the tech world evolving in the next few years.But regardless of that, Apple's position is that the device in your pocket -- or maybe on your wrist, or in your ear (and maybe over your eyes) -- is the way to go.Its products -- most obviously the Echo speakers (new versions of the Echo Dot and Echo Dot with Clock, which arrived last week), but also its Astro robot, sleep-monitoring Halo Rise clock and more -- are not things you wear or carry but are devices in the home around you.These visions aren't mutually exclusive; indeed, many of us probably live in these worlds at once, using both Apple and Amazon products."
