Seems like it is an advantage NOT to be in the very first production run
While it was true for the X25, non-e-sim, keyboard challenged first-batch Gemini (I still like mine), since they've been checking quality quite a bit more thoroughly this time, I would presume they haven't been letting early Cosmos through with dodgy components, but rather found the rejection rate of some of them to be so high that, in order to not run out of stock, they either would have had to accept parts that weren't quite up to spec, or order more and wait for them. Apparently, they chose the latter, which I think was the right choice.
While a six-month project running six months late, cannot be okay by any metric, doing things right is far more important than trying to save a few days. When it ran late, they tried rushing the Gemini, at the expense of quality. At least, it seems they're not repeating THAT mistake again, but before even considering a third device, I think they need to get to the bottom of these delays. If nothing else, they may have to humbly accept that a project like this takes about one year, and plan any future crowdfunding accordingly.
