Is it working well?
For the most part. Animations such as Glances have some stutter, even with transparency turned off. And loading apps like Weather take too long for just a small snippet of information.
Did you buy the right watch/size and band for yourself? Recommendations?
My wrist size is about 175 mm and I got 42 mm stainless steel with Link Bracelet. Bold yet sleek. It's beginning to show signs of wear and use. Beautiful work of craftsmanship.
Girlfriend has the 32 mm stainless with Modern Buckle and Sport band. The Sport band is great. It has a silky feel to it and very comfortable and I value the tuck-in design. I've heard the leather texture on the Modern Buckle described as cheap, having the look and feel of glob that's been extruded. I don't share that opinion. It has a smooth finish and looks better without stitching. The clasp mechanism is simple and beautiful.
What Apps do you like best ? Which Apps suck ? Which apps are a MUST HAVE!?
I don't have third-party apps installed as they're painfully slow. Of the native apps: Workout and Activity are my favorite and a big selling point of the watch for me. And oddly enough I'm a fan of the time-based apps: Alarm, World Clock, Stopwatch, and Timer are used fairly often and I have them all as complications. Calendar is great for quick glances at your schedule. iMessage is surprisingly fun, and especially Digital Touch. Finally I get to send obnoxious messages to the girlfriend in the shower.
And not that I think these apps suck per se but I don't use Stocks, Music, Remote, Passbook, Camera, Photos, Mail, Maps.
What's your advice for the first day when people get their Apple Watch? Prep work? Do or Do nots?
I would suggest turning off notification sounds. Or muting the entire watch. While I'm sure the design group put in considerable effort into creating the watch sounds—and they do sound great—I couldn't get used to my watch emitting dings and bells 90 times a day, especially at the dinner table.
The only notable do not is do not baby the watch and worry over cosmetic blemishes. It's a watch. It's a tool designed for use. You wear the watch, don't let the watch wear you. You don't hear guitarists complaining about scuff marks or belt buckle dings on their $5,000 Les Paul.
What's your opinion of the Apple Watch now that You've had it for a week or more? Do you love it more? Like it less?
I get watch withdrawals more than phone withdrawals. It really is an intimate piece of hardware. It's pretty much everything Apple advertised it to be.
Regret your purchase? Excited for new updates and features?
Nope. Happy to be a first time first-gen user.
