Someone reacted to my argument about the iPhone Duo potential naming:

@numericcitizen @daringfireball I had a Duo 230 and loved it. The thing that made it Due was not that it was two complementary pieces of hardware. It was that it served two functions, laptop and desktop computer. This iPhone looks like it is going to serve two functions, phone and tablet. We'll know more when we see it introduced, but I think those two functions align with the Duo name.

I think he’s right, and my argument was flawed.
