I finally bit the bullet and signed a new contract so I could get a "free" "upgrade" a few months ago.
My phones:
(a bunch of dumb phones) > HTC Evo > Motorola Photon 4G > Motorola Photon Q 4G LTE
I miss the Photon, but Sprint finally went to 4G LTE so I had to upgrade to the Q. The phone feels like a downgrade overall though with non-replaceable battery and no SIM card. Also, the on screen keyboard is ****e, the Photon was better, but the Q has physical keyboard. Q is not bad but...
I am pretty much a Motorola fanboi, everything else has disappointed me. Got rid of the Evo because it couldn't charge fast enough; in the car running Trapster, Waze, or any other GPS enabled app I would need to take several spare batteries with me for a 4-hour road trip because it'd keep running them dry even when plugged in, that was its main failing. I passed it onto a friend who had a phone incident before her contract was up and she loves it though. *shrug*
