Thanks all.

I'm tempted by the top end 8gb i7 with 512gb Surface. I always grumble at myself if I don't get the top end even if I think I can move down. It is better to hurt now than later!

It looks like the docking will give me my two screens. However I'd want to buy it from John Lewis and they are out of stock.

I know that forums only tell you about reliability issues, but is there much of a perception of problems yet? I'm reading of bluetooth issues etc.

Thanks for any further feedback / comments / pointers.
