As such, even the reviewers can't quite figure out what to do with it, either.
Radically different from the dozens of other offerings? Like Samsung, Motorola, Pebble, LG, Microsoft, etc.?
They all do (or did) the similar things. Not sure what’s so radical about “it’s a toy and doesn’t sell, even after 20 years of development”.
Ya know, it’s OK that Apple hasn’t completely figured out what to do with this thing. That’s what’s great about new platforms: customers can figure that out. As an app writer, I’m excited to see what can be done with this. People didn’t know quite what to do with the iPhone at first either, but the results indicate pulling that stunt again is probably a profitable idea.
