So I'm just wondering what is the percentage of Apple Macbook and Macbook Pro users who need the internal CD drive. I personally need it only every 3 months or so, and could happily live with having an external drive. Looking around on the market, this would make it possible to make an Apple laptop of 4 ponds or less in a 0.8 inch or less chassis. So let's do this very simple binary poll: who'd prefer to have an ultra-portable laptop to one with a CDROM/DVD drive?
