I would guess that most of the people here come from the engineering field...;) - and while what you say is true to a certain point when i compare the comos state of release with other headsets at the point of their release it becomes obvious that there is a difference in what we seem to consider "prone to issues"...
i just gave it another shot with the new firmware - beat sabre, pistol whip, audioshield, ...whatever you want - while beeing a lot better since when it came out it is a hell of frustration if you have ever played on a different headset...i moved 3 new lights to my playroom to get the "too dark" thing gone, but the tracking is not even close to my odyssey+ (which i have a lot to complain about - no question)...but the tracking worked from the beginning - same goes for the oculus quest...again - we seem to have a different opinion on "works fine" it seems - or you dont have experience with other devices...i dont know...
I for myself decided to keep my cosmos for seated gaming and development - for me its the most comfortable device i have tried so far and also the visual quality is completely on point for my personal standards...but the tracking and the controllers are still in the category 'useless' from my point of view and experience...I still have hope for the next updates but realisticly i think if they didnt get it to work till now it seems to require a hardware update...so speaking for myself - currently i think this was my first and last HTC device - its ok for flight simulations (or stuff like elite, eve, ...) or development but a bit too expensive for that...
And from a customer point of view i myself would appreciate if (but this goes for any VR brand on the market) HTC would focus more on the hardware development and not on having another seperate store on the market...i myself feel like the most (or too much) effort during development was put into having other place to sell software on than on putting together a working device. I myself dont care about any store where my money is wasted the moment i get another device - but maybe others do...i dont see the customer benefit in that....while i would see it in a working tracking on the cosmos....;)
