To the question, the weight was _one_ primary factor in my purchase decision. Nearly every other consideration was around the issue of portability as well.
Even though I purchased the larger heavier 13" due to my preference for a larger display, it's very thin and light as compared to my 15" mid 2010 Core i7 MBP. The MBP is perfect, I carry it to the office and other places daily. Yet I also travel internationally, therefore the MBA is perfect of use in the plane and in the airports during layovers.
At the end of the day, I also find the styling even nicer than my original MBA. I'm very happy that Apple did not abandon this model.
