There was a major performance advantage to having a real PC to gig with but I do not think things intergrated as wells as I would have liked. The wireless features helped a lot.
Right now, I am using a laptop but I use a real wireless keyboard and mouse (wireless) and my 19" falt panel. I have found that flat panel monitors intergrate well with a DJ setup. I try to use the controller as much as possible but sometimes I have to have a keyboard or a mouse handy. Having these components wireless means I can tuck them away easily and use them from anywhere stationed around me.
Sometimes, this is all too much a pain to setup and I just have laptop but I always find it easier to attach a real wireless keyboard and mouse. I use a light weight BElkin keyboard, its wireless and a pretty small foorprint.
The pains of being a digital DJ.
