I love the apple watch very much! It was well worth the price and has already changed what I do and how I do it, for the better.
I got turn-by-turn directions in the car, spoken to me, with the directions on my watch, and a different buzz for turning left and right. That was awesome!
I have been speaking my texts, finishing in about 5 seconds for a paragraph that would have taken me 1 minute ordinarily. All without taking anything out of my pocket.
I've checked stocks by simply swiping my finger once.
I made a phone call in the car by saying "Hey Siri, call Andrew". Bam, bluetooth through car stereo.
I get text and email notifications with different buzzes and simply raise my arm to see if they are worth it. If not, I just put my arm down. I yes, I read it, then if I want to respond, I take out my iPhone. If not, i simply put my arm down.
And more!
And this is just the first few hours!
It's absolutely amazing. And, it's beautiful (SS Milanese).
I highly recommend the Milanese band. It is worth it for the look, feel, and variable fitting.
You come to understand what it can do more and more, so I think the people who say "meh" are mistaken and will change their opinion in 1 week. If you just break it open and play with it, it doesn't seem too fabulous, but that's because you're not actually using it in practice.
To answer your question, if you can wait, wait. If you can't and have money to burn, go for it, as you will probably love it, but I would try to find one from someone who actually seems like they are legitimately selling it, as opposed to simply turning a profit.
