I can't decide whether I want a Lumia 920 or a Surface Tablet

I didn't say that was the case either, it was more about it not really interfering with one hand use rather than making it better.

True, as long as you can wrap your fingers around it. It might affect pocket-ability because when I had the Xperia S(10.6mm thick) it was actually harder to sit in tight quarters than it was with the One X and GS3, despite the Xperia S being a lot shorter and smaller lengthwise.
