Perhaps we can fire up a poll to see the interest. Just to see who owns what device, and what interest there is them as gaming platforms.
Essentially, do you see them as a gaming platform in their own right, or are they just a novel way of passing the time until you get home to a 'big boy' console? If there is enough interest, then certainly adding a prefix would be a start. if not starting a Division for them. (This could overlap the other mobile devices too, but I tend to agree with Ebonytears in that they would be better grouped with their respective big brothers.)
Anyway, as an iPhone owner I would be interested in pursuing this subject further.
There's my two cents.
