sadly I am not too surprised at the glitches, as my default expectation is that when a launch date is announced, production always lags behind, and quality control may be rushed to meet deadlines - indeed I think any preorder should be at a discount.
It may be just me noticing things selectively, but this problem seem to happen with the majority of devices being launched, regardless of brand, which is why I've stopped myself from preordering anything ever again, burned too often... Yet, I still very much look forward to seeing an Aura in the wild, and taking the plunge about Christmas time
