Surely bigphone uses are more likely to be wearing cargo pants than skinny jeans?
On a more serious note, it's not entirely impossible to use several devices - both Android and iOS seem to be pretty good at syncing multiple devices (I have no experience of Windows mobile but I suspect it is the same). It would be nice if devices could share numbers, but some judicious call-diverting does most of what is needed.
