Let's say that there is scope for differing opinions about the "perfection" of some of what you cite for NOW. In particular I would not regard Easyjet's home base as the "perfect location" for another low-cost. And as for "good route network selection", the jury's out on that one in the absence of a definitive list of destinations. Low-cost is a popular trend which established itself in the UK a few years back but "*being* taken up" in the UK? I think it *has been* taken up... and then some: the market's saturated.
In addition, you didn't mention Now's wrong-headed flat-rate pricing model which - IMHO - was on a fast track to nowhere.
Somehow I think these might be a couple of the reasons why the investors steered clear.
Happy to debate this over on the Now thread if you want.
