So I finally got it deployed and I am very happy with it (as are other members of the household).
Something I learnt as a by-product of this project is that even for just on a desk. A 45 degree backbox makes a perfect stand for the LocalDeck having it at a higher angle and allowing you to use the rear USB port easily and can easily be mounted anywhere or just tucked under a monitor on your deck.
Definitely will be looking to get another one at some point if/when I can justify it. Probably when the hardware revision comes along.
