[Asus ZenWatch] pedxing:
Less than 24 hours with the watch, but here are some initial impressions:

Build quality/Design: Excellent. Definitely has a premium feel right out of the box, the band is very nice with the interior having a very nice soft feel against the skin. The thinness is admirable, it is a big improvement over the hockey puck feeling you get with the Moto 360. Only a couple mm but with the rounding of the display, it makes a world of difference. The bezel, while large, is not a noticable defect. It goes with the rest of the design just fine.

The band clasp is very good -- I'm a fan of the pole and clip design. Easy on and off, plus adjustability. In addition, a nice little feature is there is a small slide on the inside of the band making it exceptionally easy to change the band out with any other 22 mm band of your choosing. No tools are required except a fingernail. It could not be easier.

Display: Very bright and colorful. I have it on the lowest brightness and it is completely adequate for nearly all of my use. The PPI is noticeably less than flag ship phones out right now, but in no way does the display look grainy or blurry, even at extremely close distances. One issue so far is that the movement-based display activation is not quite sensitive enough for me. It doesn't always come on when raising my wrist. It seems like you need to move about a foot for it to activate. If you have your wrist up already (like in a typing position), flipping your hand to check the time is not enough for it. There's an "up" motion I think that is assumed.

At this point I still think the square display is the right choice due to how most cards are displayed.

Battery: It came at about a 50% charge and I wore it down to about 20% in a couple of hours of non stop playing. Recharge time is about 1% per minute. After charging it to 100%, I put it back on and ran "Sleep as Android", an app used for sleep tracking. In 8 hours it went from about 95% to 36%. However I did have notifications still enabled for about half that time. After each one, I thought it would be the last because of the lateness but after about 4 hours I turned them off. Also the screen was set to auto off during this time.

After about 4 hours with a LOT of notifications and a fair amount of playing, I am at 78%

Google Now: Mic sensitivity seems good, no problems working the voice control and having it understand me, even in the car. The normal cards came up no problem this morning -- a couple of weather cards, drive time to work was 10 minutes more than usual plus a shipping notification for UPS.

Asus Apps: Seem to work well. I customized a watch face and set up various things like the find watch, find phone with no trouble. The remote viewfinder camera app is excellent and works perfectly.

Oh -- the heart rate sensor seems reasonably accurate. If you fumble around it will give you something bogus, but hold still and you will get a reading in 10 -15 seconds. You touch two fingers to each side of the metal frame to get the reading -- similar to gripping a sensor on a treadmill or exercise machine.

Other apps: So far I've played with a few apps.

Music Boss (for Wear) -- Works great for controlling any media app, use it with netflix and chromecast, or play music, whatever

Sleep as Android -- seems to provide very good stats for your sleep although the battery drain could be better. But it works, Moto 360 does not.

WearTasker -- I've linked this to my home automation to turn on lights, unlock doors, etc

Google Keep -- Trying this out for shopping lists

Bring! - Shopping list

Calculator -- Because old school

Yaste -- XBMC home theater control on your wrist

Compass -- because coolness
