Much better device than I'd hoped. Can't wait to see what third parties do with this.
Dark Sky, Clear, and a great podcast controller for starters. A tip calculator and Shazam (or the like) would not go amiss. But the stuff nobody has even THOUGHT of yet that's exciting.
For input we have:
- Touchscreen swipes, scrolling and taps
- Screen presses
- A wheel for scrolling and zooming and cycling options
- A button (well, two, but I'm assuming a press on the wheel is entirely OS-controlled)
- Voice mic
- Proximity sensor (since it can silence a call by putting your hand over it)
- Tilt control (not sure about a magnetometer?)
- Heart rate monitor
- GPS relayed from the phone
- Notifications relayed from the phone, with custom actions and "glance" panels
- Live camera view relayed from the phone
And for output we have:
- Screen that doesn't need a "shake" gesture (but sadly can't be "always on"--that's physics for you) and doesn't cut off the useful display corners for the novelty of "nearly round"
- Speaker
- Silent haptic taps in different patterns (you can tell who a message is from) with no annoying audible buzz
- Round trip back to the phone: automatically bring up the same email (or whatever) you were already looking at.
That's a lot for devs to work with. Throw in 34 different watch models at launch (not counting third-party bands) and I'd say we have a winner. Even if I myself would rather wait until generation 2. Everything new gets better--and cheaper--with time!
