Got the T2 last year and I think I want to go back to a slightly smaller phone and return to the Turbo.
Refresh my memory, what does the T2 have that the original Turbo doesn't, aside from the processor and the micro SD
Shatterproof display. Marshmallow. Not just the processor, the gpu is better as well. Better "selfie" camera. Slightly better rear camera. Bluetooth 4.1 instead of 4.0. Dual wireless charging (qi and pma.) Smaller battery, though.
A turbo, if you buy it used, probably had a slightly worn out battery.
I'm with you - I still hate these bigger phones.
