I agree. Response to early glitches means everything. Helps a lot if CS reps are quick to acknowledge caller concerns and respond to them with concern rather than the much more common 'well, that is not a known issue [implication: its just you, so deal with it].
The nature and scope of bugs matters too. As these forums show plenty of users are willing to ride out the voice-quality thing until there is a fix. In contrast random and boot loops are a lot harder to live with: immediately and perhaps permanently disabling..and after 30 days, all bets are off. In short, the repetitive (read: affecting multiple devices) unpredictable or disabling problems are the deal-breakers. For some, that includes call quality. For others, its different. As was stated above, different strokes for different folks.
Very interesting to see that the posters who went completely mad waiting for long-delayed shipments from at&t and Amazon wireless are -- best I can tell- largely absent from the TITAN bug threads (jenashley!!). There was something about that 2nd (or 3rd) wave of shipments that may have been worth waiting for!! Glad the torture of the initial wait paid off for those folks....would be especially awful to wait like that and then get a bum device!
