I'm pretty much the complete opposite. Veeerry infrequently I might peek from a mobile browser but 97+% of the time I'll be interacting from Safari or Chrome; in fact I can't think of a time I've actually made a post from my iPad (and wouldn't unless I had the bluetooth keyboard going in which case I'm halfway to laptop).
Might be interesting (and someone's probably done so in the past) to look at the user agent info and see what people are actually using rather than anecdotal self reporting.
