If you run it on a tablet or laptop
You can take it with you and prepare new performances
Comfortably on the couch next to the misses..

I never sit more then 2 hours behind the keys
The rest of the evening there is a social part called fammily
Which requires my attention in the living room

Reading, talking, watching tele, or ipadding.

It would be great to be able to prepare your music from the couch, using a tablet...
And that can only be done with a full software setup..
