Well, I have the best of both here in the same spot. I have my laptop hooked up and on the slide out shelf under my computer desk, and my sewing machine sits on the desk it self. I can sew a while, then push back just a foot and pull out my laptop and get to this board. I "pretend" my laptop can't move from the slide out shelf so I am never far from the sewing machine. In fact, I leave the lap top plugged in. Half the time I forget it is a lap top.
Works for me. I can't sew and be on the computer at the same time, but this is pretty close!!
