There's a lot of examples in the Look What I Drew on My Phone thread that illustrate the creative potential of the resistive screen. Not that it's impossible to create art in other media, including a capacititve screen, but, like oil versus acrylic, it would be a different work in a different medium.

My other thought is cold weather use. Those so-called "touchscreen compatible" gloves really aren't warm enough when it's very cold out -- at least not for me. I suppose that's the reason that in-car touchscreens and those on gas pumps are still resistive.
