I was going to bring up the car argument as well. However, someone beat me to it. That being said, obviously cars (I'm not going to keep it to just Lexus) don't go through as much vetting as you're saying they do. It seems weekly there are recalls for cars in the hundreds of thousands, if not millions. Cars, an object that has been in production for 100+ years still has manufacturer defects, some that cause death, at a much higher price tag than a smart watch, which category is new to the last decade.
I support Apple, however, I feel I'm able to understand when things are wrong. I felt my Mom's watch had an issue with the band locking into the housing and this was reiterated on MacRumors and I posted that I encountered that issue. However, some of the issues you mentioned don't seem to be issues justifying your argument.
From what I have read, and I could be wrong, no watches were shipped with the haptic issue. I was under the impression that this was found early enough but it has caused short supply and longer shipping times. Again, I could be wrong.
The tattoo issue is an odd one. I would maybe have expected Apple to mention it beforehand, but in asking them to say it wont work with some tattoos, you're then opening them up to have to tell about every scenario it will or will not work. From my understanding, it isn't limited to just the Apple Watch. Any watch using the same method for reading hear rate is subject to error. Is it mentioned on the other products? I'm not sure, but I would doubt it.
I think your argument is valid, however, I think maybe not for this product, or not for the issues you mentioned. You also have to look at the other side. As I mentioned before, some other heart rate devices might be susceptible to a reading error when in contact with a tattoo, are those companies being called out and blasted like Apple? Is there an uproar when every other company releases a product that isn't perfect gen 1? I think Apple is held to a higher standard, and they should be being the company that they are. However, I think that the the Apple Watch lives up to the Apple name in regards to what you get.
