What is "assistance with various things?" That's incredibly vague and unhelpful. What is "a companion device?" Again, vague and unhelpful. You haven't explained anything, and the web site fails to explain anything, and I'm being too harsh?

There is zero information on the web site except an overly long video badly aping Apple's product announcement style. Including as-seen-on-TV "doing things is so hard" crap.

Hell, the FAQ is entirely about purchasing, not about the "product." It's therefore also meaningless. Rather than harsh I'm being generous. This web site is useless.
