So if I connected a controller keyboard to a computer running Linux, then it would automatically become a Workstation/Arranger that I could play, edit and perform all the functions of a Workstation/Arranger straight away with no work involved, and also be a perfectly acceptable piece of furniture in the lounge.

As you obviously already have experience of this, what controller and Computer do you recommend that would achieve this in a similar time as unpacking an MS and switching it on. I would also be interested in the best way you have found to integrate it into the lounge as a piece of furniture.
