I got to disagree....You guys are not considering the "track performers"..as we know many ladies doing a single with laptops...

This unit is all self contained including effects with mic inputs,,,video outs if you are Karaoke...and the make up tools and markers, with a large enough hard drive...USB midi to use with a keyboard controller...Mixer is also built in..
Sure it lacks style play that all "Pros" rely on..

You guys are not looking at the whole picture...just because it doesn't meet your needs...it can meet the needs of other folks working in the "trenches"..
