And yet I have only once used the USB OTG on my phone... nice to know that it is there, but I have never had cause to use it, other than to check it worked (ahem, XBOX USB controller on a Megadrive emulator and VirtuaRacer).
My point is that for some people (usually not Reg readers) their laptops are for typing, spreadsheets and messing around on the internet- USB isn't required. Reg readers are likely to research and then buy the kit that suits them - so they are not likely to buy this new Macbook.
My laptop has six USB ports and I'm glad of them. However, what I'd really like is a single cable to a docking solution.
