OK - so today set up the pro as my laptop replacement at the office. USB3 Hub, external HDD and Monitor, plugged in the charger, USB Hub and Micro DP, all worked really well - apart from the scaling on the external monitor - only when you plug in a monitor you are used to (in this case a 24" 1900x1200 job) do you realise just how much real estate you lose. Right now I think the alternate font size on external monitors would be my highest priority on the MS Surface Fix list. Anyway - one thing I do think is that the charger USB is a real missed opportunity, if the USB port on the charger was fully functional rather than just providing power you could have a really tidy single cable docking solution - just by plugging in the charger. It's a great idea being able to charge another device from it, but going that step further would be tidy!
