Yes. Mine arrived on 4/24 and I've been wearing it every day since then.
My day job happens to be iOS app development and I wanted to jump in early to get a feel for what it was like to live with it, what new interactions enabled, and how we could improve the lives of our patients by extending our app onto it.
I'm working on my first app for the watch on my own time. It's a fun place to play right now, because there are lots of oddities and nuances that you have to learn about through experimentation instead of searching StackOverflow.
I bought the 42mm Apple Watch Sport in Space Gray with the black sports band. When they first announced these, I expected that the smaller 38mm watch would fit my dainty wrists better than the 42mm watch. After experimenting with some full-size cut-outs, I went with the 42mm version and couldn’t be happier. I highly suggest if you're thinking of buying one of these, make an appointment and go try them on in the store. The 42mm is not huge at all, close in size to my coworker's Pebble. It’s quite comfortable and though you’d expect something that’s flat and has corners to be uncomfortable to wear on your organically-shaped wrist, that has not been an issue.
My one reservation in buying the cheaper Sport version was the band: I expected it to be similar to the old Timex Ironman style watches, or worse, a soft silicone that picked up lint and dirt. I was wrong. For the first day or so, every single person who picked up the watch had the same reaction: wow, that band feels nice. After a week wearing the watch for most of my waking hours, I agree completely. It’s just comfortable. It contours to my wrist without any pressure, it doesn’t pick up lint or dirt, and it doesn’t snag on my arm hairs the way some metal bands do. I didn’t expect to like the novel way Apple dealt with the “tail” of the band, but it’s actually quite comfortable. With my tiny wrists, there’s usually plenty of band left over with a conventional watch band. That leftover bit sticks out, gets caught on things, and is generally a pain in the ass. Not a problem with this watch!
The aluminum casing makes the Sport watch the cheapest of the lot, but also the lightest. I don’t feel like I have a lead weight attached to my wrist, it’s just … there. I don’t know how much heavier the stainless steel or gold watches are, so I can’t compare, but don’t worry about being weighed down by the Sport version.
That covers wearing the watch. The only thing I’ll add here is that even when wearing short sleeves, the watch does not seem to attract unwanted attention. There have only been a few times I’ve been asked about it just by wearing it. I have gotten a few questions when I start using it at inopportune moments (more later).
Utility. So it’s a pretty, albeit comfortable piece of jewelry at this point in the review. Why the heck would you buy one when there are much nicer timepiece-only watches for the same price?
It’s not an earth-shattering revelation. It’s not a life changer. Yet. I expect watches like these will be (almost) as ubiquitous as smart phones are today. Remember when no one knew why you’d ever want a smart phone?
The more connected your lifestyle and the more Apple-integrated those connections are, the more you’ll get out of this watch. On my watch face, I have the usual date/time stuff, plus the local temperature, the watch battery level, and most importantly, my next calendar event. I’ve tied my work calendar into my iPhone, which means I can see at a glance not just my personal appointments, but also the time, name, and location of my next meeting. I love this feature. Tapping on this meeting reveals a list of all of my upcoming meetings/appointments. Very useful.
I did not tie my work email into my watch. I get too many off-hours emails that do not merit my attention, so for now my watch only alerts me when I get a new email on my personal account. It’s a fine way to glance at the sender and subject of an email as it comes in. Which brings me to my next point.
Alerts. We’ve all gotten used to “phantom buzzes” where we think our smartphones are buzzing when in fact it’s sitting there quietly. I’ve found the “haptic” alert engine on the watch to be incredibly effective with a low incidence of false alarms. Really, it feels just like someone is tapping you on the wrist. There’s a sound too, which I feel a little odd leaving on, but that is subtle enough that I don’t worry about it (too much). In sum: if you rely on alerts from emails or SMS to keep your life flowing, you’re going to love this watch.
Doing things: Siri is your friend when wearing an Apple Watch. I’ve generally used her to send SMSes, and once to get directions home. She works OK in both cases, though I do feel a bit of a fool talking to my watch. And you still need to interact with the screen to confirm input, hit send, etc. The favorite contacts interface is novel and surprisingly effective. Navigating the app screen is novel and slightly more frustrating. Glances are less useful than I expected, but will improve markedly, I expect. Using the crown wheel to do things is becoming more natural. If you can’t do it in a few taps of large, simple buttons, it’s not worth doing on the watch. I have yet to pre-load personalized SMS responses, but that’ll happen and will make the SMS interactions far more useful.
Battery life: I don’t use my watch constantly. I wear it all day, glance at it frequently, interact with it a couple times an hour, but I’m definitely not a power user. I have yet to run the battery down completely in the course of a day, even a 19 hour day (oops). Excellent.
Etiquette. I don’t think this has been established yet, but it seems fairly straightforward: don’t be an ass. Sadly, since your watch is right there on your wrist and doesn’t have to be dug out of a pocket, here’s a temptation to subtly open and skim that new email the instant it comes in. At this point (and having fallen into this trap a couple of times), I’ll note that you’re never as subtle as you think and actually using the watch is a two-handed operation. Lift the watch hand, use the other hand to interact. Not subtle at all. I feel a lot more tempted to glance at a notification when it’s on my wrist than when it’s on the phone in my pocket. We’ll see how that works out.
The damn Activity app. One of the default apps allows you to set some activity-based daily goals (calories burned, minutes of exercise, standing time per day). Early on I set it to something simple. Now if I sit at my computer for over an hour, engrossed in code, it'll tap on my wrist and say "stand up and move around". And I do it. I'll take a walk around the cube farm, interact with a couple of people. When I get back to my desk a couple minutes later, I honestly feel better. This is one of those things I didn't expect when I bought my watch. It makes one healthy habit that much easier to keep. Also, it's been tracking my heart rate every 10 minutes since I got it. I'm not sure what I'll do with that information, but I'm a data guy, it'll be useful at some point.
Overall, it allows me to keep on top of my schedule better, it allows me to keep on top of my personal email very easily. It makes sending some SMSes much easier, and makes responses to basic SMSes incredibly easy. It's a great health device (not just activity, but it makes tracking my runs much easier, as I don't have to wear my phone in a ridiculous arm band).
It's not a great telephone mouthpiece. I've done that once "for real" and once just to show how ridiculous it is. It's not Dick Tracy, it's dickhead. Talk into watch. Move watch to ear to listen to response (half-duplex). Try listening to your watch/wrist right now (Not you Tom, keep that shoulder immobile!). Isn't that a ridiculous pose? Yeah.
How's that for a review?
