Still playing with dummy units while shopping for your next phone at your local retailer? Those things are annoying, aren't they? You can hold them in your hand, but you can't touch or interact with them in any way.
Best Buy may just have the solution. You'll have to take a few steps back in order to see the new Nexus S demo unit in all its glory, because it's a fully functional 42" monster, complete with a working touch screen, live wallpaper, apps, and everything that a real Nexus S contains.
