N9 for phone/twitter and offline maps/GPS and as a bluetooth PAN server. Tether to iPod touch, Nexus 7, and laptop(when i need to). My main profile is N9 and iPod touch together. All the commercial apps plus a real linux phone. I also run an Ubuntu chroot on the N9 and connect to it over VNC from a Nexus 7 for real LibreOffice and in the future, Qt Creator for mobile Qt development.
