@Charlie Clark Re: "need to be compatible with docking stations and Microsoft........
..........won't have any of those until 2014".
Interesting that you should say that as I just spotted the following at a Norwegian site (I live in North Norway):
The site indicates that they are expecting delivery at the beginning of November. From the site:
3,5 mm audio
3,5 mm out
USB 2.0 port x 3
USB 3.0 port x 1
RJ-45 Fast Ethernet 10/100 Mbit/s
If this is correct then MS have taken that point on board, although I have to say that I do not remotely understand why they did not release such a peripheral with the first Surface Pro.
