Thanks james for your reply.
I'm a little bored to reply here, because also for my not native english language, I can not explain all.

If on the OL the basic application is the Reaper for produce professional music, do not forget that this features is FULL working on the Groove too: http://www.lionstracs.com/demo/reaper22.jpeg
here you can see the Reaper on external 22" touch screen, ( we can use now 3 external touch displays)
with the difference that we can run multiple ASIO hosts or VST inside the repare, + the all OS 4 basic application.
Read here and then you can understand what I mean: http://forum.openlabs.com/index.php?showtopic=1569
