It could just be a transitional fragmentation. It is confusing that the Macbook Air is now the default Macbook, and something called a Macbook is a bit niche like the original Air was, but in a year's time the product line up could look a lot tidier - eg, a MB form factor is retired, beefed up or given a new display.

Respectfully, I disagree. Whether or not this watch is the correct solution, I don't know, but a time-and-motion study could show you empirically that allowing notifications to be dismissed or ignored without pocket-fumbling is no bad thing in principle. For some people, that function alone would be of tangible benefoit. Personally, I think Citizen and Casio are on a better path. But that's just me.
