I use this stand both at home and live, and it is a solidly built, reliable unit. I'd recommend this to anyone who'd want to keep their expensive laptop closer to yourself and on this side of the show, rather than, say, having it on a stand that sits on top of your keyboard which would be way closer to a dancing crowd than I'd feel comfortable with.
The mouse surface can also double as a stand for the audio / MIDI interface or any other smaller piece of gear.
The only thing is that these things don't bend and must be assembled / disassembled each time. Material and build are solid though.
