I spent about half an hour in the store with both and could not convince myself it was worth it. Sure, its better, just a tad bit really.
- Screen bigger yes, but what actually is displayed is the same size. I compared Google maps side by side, the map was 100% same size on screen on both devices. T2 had extra screen below just for the buttons. T2 was a tad brighter though, which is good to see.
- Camera, definitely a little more snappy. I did like the front camera being wider, but im not really a selfie taking person anyways. Camera still needs optical image stabilization in my opinion after a few shots I took.
- No Marshmellow. Both dont have it of course, but buying a new phone and waiting until next Summer to get it, while HTC/Nexus come with it right now, is frustrating.
- No fingerprint scanner. Other phones come with this now, making them much quicker to unlock.
Everything about the phone just felt like I was playing with my T1 with some minor tweaks. I'm still debating about whether to upgrade. Turbo 1 is a fantastic phone, so its hard to improve on whats great. Just wish had a few more tweaks to justify $600 - like Marshmellow, fingerprint scanner, OIS, wireless charging..
Lasty- I could care less about the shatterproof screen. T1 already gives you 1 free screen replacement, and I have the insurance on top of that. Plus, ive dropped my T1 at least 10 times outside, and not a single scratch yet.
