Nice review,we appreciate the time you took to write & post here.
As you mentioned,this phone isn't actually available ATM.
While most excused OnePlus for this sort of thing,along w/the drama of the invite systen from last years offering,seems most aren't willing to go for seconds,I know I'm not & from the look of things in this forum,compared to last year,not many others are either.
The hardware is only one part of the equation.
Software & customer support,real customer support,is just as vital,especially when competitors have it.
OnePlus is seemingly arrogant.Perhaps their games fly in other markets,but,my money says they're in for a dramatic drop-off in sales from last year.
I enjoyed last year's offering,but,the market is literally flooded with equally equipped phones to bother with OnePlus for another round of B.S.
Count me out,best of luck to those that opt for this phone,whenever OnePlus deems your market is worthy...............
