Joining the theme of "My First 24 Hours" (42mm Stainless Steel with Milanese Band):-
1) Styling - I like it quite a lot. I can see how we'll be laughing at the chubbyness of it by version 4 but for a version 1 it is nice. The Milanese band looks smart and I can use it at the gym too without having to swap bands.
2) Interface - needs some work but it's OK - Glances are a somewhat bizarre hybrid between a notification, a launcher and an app - I haven't worked out what they're really good for yet apart from a "fast launcher" for the 3 or 4 apps I care about (Now Playing, Overcast, Alaska Airlines, Stocks and Weather). Make sure you change the sequence of them to your liking. The cluster of icons home screen could have been replaced with the regular iPhone app grid and been just as good ... probably better.
3) Killer App - for me at least - my daily calendar on my wrist with good details for each appointment. Touch the appointment name on the watch face and it launches the Calendar app. Also like the remote control for music/podcasts. Everything else is just icing on the cake.
4) Functionality - tons and tons - perhaps even too much for the non-technophile and a Version 1 product - this watch does almost everything right out of the box - Apple did an amazing job on the features.
5) Input - I love all the features but I could see how many folks would be confused by the 14+ inputs you could do on almost every screen (tap somewhere, force touch, swipe (up, down, left, right), turn digital crown, press digital crown, press and hold digital crown, double press digital crown, press side button, double press side button, press and hold side button) - these all do different things.
The general rule is "THINK iPHONE" -
Digital Crown = iPhone Home Button (press for home screen, double press for app switcher, hold for Siri). Side button is a little like iPhone Power Button (hold for Power options) but also does Apple Pay and Contacts which makes it a little different.
6) Watch Faces - unlike some others I am not as impressed - they are either beautiful but not functional (jellyfish, astronomy have basically no customizations) or functional but a bit plain looking (modular). We need a few more beautiful but customizable ones. I would also like control over how long the watch face stays on when I raise my wrist (like everyone else). Let me decide if it's worth the battery hit or not.
7) Missing Apps - no Reminders app? This is a HUGE missing piece for me. I want to see my action items/to do list at a glance, please. Find My Friends would be good too (my kids coming home on the school bus have older iPhones and I use it to know when to leave to meet the bus).
8) Taptic - not impressed yet. Even with it switched to "Prominent" I can still miss them. Even with strap on tight.
9) Speed - not bad, a few waiting moments here and there but not an issue. Faster is always better of course.
10) Brightness - I have it turned down to lowest setting to preserve battery and it's fine for me.
11) Text Size - I have this switched to smallest and I get a decent view of daily Calendar. YMMV.
12) Missing info - when my watch says "Connected" I'd like to know over which network - I have found a few bugs with wifi but it would be good to know if the wifi connection is working versus depending on Bluetooth. I could imagine issues with multiple wifi networks too. Also like to have the option to know when I have left my iPhone behind somewhere as I leave (a bar

for example).
13) Siri - like others I find it a bit buggy - sometimes complains it can't connect, then I try again and it works just fine. Part of the wifi connectivity issue I think. Otherwise fine - wouldn't mind the option of voice feedback too (esp when I'm driving).
13) Bugs - main ones I find are that the watch doesn't come on reliably when I raise my wrist - also give me a sensitivity control for this? Sometimes it comes on but goes off after 1 second. Not working reliably over wifi - sometimes it's happy 200 feet from my phone, sometimes it complains it has lost connection. iMessage was giving me errors until I logged out and back in to iCloud on my iPhone.
14) Battery - seems ok - loses about 5-7% an hour with moderate use.
Overall its almost exactly what I was expecting - a feature-packed watch that looks good but has some rough edges to be expected with a Version 1.0. I expect most of these will get fixed in upcoming software updates. I expect the features/apps I use the most will probably evolve over time.
