Actually, for some of us, moving on to a new phone makes it easier to develop for the old one. My Spec is my daily driver. Once my Spec is no longer my daily driver, I can finally go hog wild with some of my theories that may perma break my phone. TDM has been running a Nexus4 as his primary for a while now, but still rocks out ROMs for the Spec and the Nitro, he just has no data plan on the Spec.
