Then I bought a Handspring Visor (a Palm OS-licensed handheld) and later the Handspring Visorphone GSM module for it. When I used that to show in 1998 how to access the Internet via CSD (that's dial-up on mobile folks) people couldn't understand why I wanted a browser in my pocket.
Microsoft is said to be working on "wearables" but not as a notification device only (which is what most of the current crop is) but adding health and automation to it. And being able to connect to any platform.
That's where it is. People might think "I will buy a Apple watch or Samsung Gear" and it only works with those devices. A truly multi-platform device (the Pebble is the closest these days) would achieve so much more.
Obviously the die hard fans of one or another brand will go with their preferred option.But don't disconsider the impact of "non-smart smart" devices like the Fitbit, which currently has 50% of the worldwide market. Or the new Chinese products coming out at $15/unit that replicate the Fitbit functionality and more.
