I've had USB3 and it honestly isn't that exciting. I'll stick to FW. I'm going to let you sit there and think about answering your question. Assuming that the optical drive remains, like you say, is 128GB really enough for the average user? My gf has 300GB worth of documents, programs, music, and pictures. This is a laptop, she's not going to want to carry around an external drive anytime she wants to access these items. My grandma isn't going to either, nor anyone else I know. But let's argue that there is always the cloud and that eliminates the need for us to store anything on the computer. There are a lot of people who use computers and do not connect to the internet all the time. I'm a heavy user because of my audio programs and even I don't want to use the cloud for anything besides documents.
