It is a consumer laptop. I own the 2010 model with 2GB of RAM, and RAM is never the bottleneck for me. Between light gaming (Portal 2, League of Legends, Flash based internet games), watching movies, surfing the web, and writing, there is always RAM headroom. If you are doing heavy photography work, sure, the MBA might not have enough RAM, but Apple never advertised it as a professional computer.
It is a 1000$ computer, but there has always been an Apple tax. If you want to complain about Apple, I guess this is the place most people do it, so go ahead. I just don't think this is an exclamation point worthy topic.
