I agree with you about loving Apple products except for the fact that quality control has gone down somewhat.
Dust under the screen should not even be an issue with these nowadays because Apple has since gone with 'fused' displays. The dust issue some are reporting is baffling to me because I've seen how an iPhone fused display is made. But then again, they can never be too careful right?... especially when they have to rush thousands upon thousands of initial units.
I don't feel bad not getting a chance to purchase my 6 Plus this morning after lining up for 3 hours. Maybe the subsequent batches are a lot better...I can wait another week or two.
We just need to voice these issues out as early as possible to get them sorted out immediately.

Can you take pic of the dust?
