Why not wait the 18 months for the better, greatly improved one then?
Do you really really really need one now?
My guess is YES
Actually, I rotate through my iOS devices and usually jump one or two models between devices (and computers). The Apple products do have a long life, so I can easily do that. And so ... I’ve already got plans for another device first before I go for the Apple Watch, to keep my planned rotation going ... :-) ...
So, no ... I’m not going to go crazy not having one immediately. With the iPhone, though, I could tell that was dynamite and I got one on “Day Three” of sales. The Tulsa Apple Store was brand new at that time and first opened at Woodland Hills Mall at the exact time that the new iPhone went on sale (late afternoon). I went there with the intention of getting one. The line was long and I didn’t want to wait. Instead, I drove down to Dallas and got one there on Day Three ... :-) ...
I was going there anyway, and there was no line to contend with. So, you see, I was able to wait THREE DAYS ... for the iPhone! ... LOL ...
With the Apple Watch, I’ll wait until version two, because of other Apple items I’m getting first.
