I'm another still hanging on with the Bionic. Though I have an upgrade available, and I get pretty impatient with the lag, I'm considering a factory reset and then running a way stripped down phone for a few months until I have to scratch the itch, probably with a moto x when motomaker comes to VZW, as Ry mentioned. But the Bionic still does what I need it to do.
Well, I did scratch the itch a little and bought a Nexus 7 a couple weeks ago, which is great and makes the wait for a new phone much easier.
