I'm not sure how much to extract from this article but it seems a leap to state definitively that "the notebooks have been selling extremely well" and that concerns are mostly bullshit. I have no dog in the fight as I am fine with the MBP overall, but this article cites no hard data. And the sole quote from Apple references only initial sales at their online store. That's good news but it doesn't speak definitively to overall initial sales, let alone multi-month/longer-term sales. The only other quote is from an MBP supply component company and is encouraging but ambiguous and isn't about actual sales but its own internal forecasts.
MBP sales may indeed turn out to be great and these are apparently good signals as to potential, but it'd be premature to conclude from these reports that it is selling "great", relative to either historical periods or to particular expectations, let alone that it will continue to do so if it is.
If they are projecting a great 4th quarter with only a 2-3% drop off in Q1 2017, it's a runaway hit. Q1 is death for computer sales.
