These are just teething issues that every new aircraft goes through. I've flown the 787 before and I would again, but I wouldn't go out of my way to do so like I did before (I took an indirect routing specifically to get on the 787).
From what I can recall when the A380 was newer there was some safety equipment (the inflatable slide or something like that) that had to be replaced really often (something like every 3 flights) because it wasn't designed correctly.
