So I've been wearing my 2nd-gen Watch about a year now and as often happens, I'm now kind of lost if I go to work having forgotten to put it on. Being able to triage messages and phone calls without pulling out my phone is great, Apple Pay on the Watch is super-awesome, and if you use a Mac it can automatically log you in if you're wearing the Watch. Plus the daily fitness tracking is great, so I know what days I need to do more.
Pro tip: you can save money by getting the watch you want with the cheapest band, and then get a Chinese knockoff band for about 1/10th what Apple charges. I got the black Milanese Loop knockoff from Amazon for $12 and you can't tell it's not the $200 Apple band.
