Not having a backlit keyboard in the 11.6" MacBook Air, while being needlessly inconvenient, could probably be justified as it is the first of its kind, so no one can say here, as we are about the 13.3" model, that it existed before and is now pulled out. Not having it in the 13.3" MacBook Air, is unarguably a step back for the product as it had that feature before and doesn't now. That said, I don't think 13.3" MacBook Airs have ever been as fast and agile in terms of performance as they are with this current generation. So that said, while I wouldn't be down with the absence of that feature in the 13.3" model, I'll happily take the increased speed and performance as they're no longer the "slowest Mac on sale".
