I've owned the Optimus V, Triumph and now the Evo V. I love my phone - finally. With Groove IP, I make mostly free calls. I've NEVER had a signal at my house, but I actually occasionally get one bar with my Evo V now that they've updated the firmware. I'll admit the 3D is a gimmic, but I've had TONS of fun with it. 80% of my photos are 2D and the camera w/flash is actually pretty good for a phone.
I hated the Triumph for it's dang-near constant rebooting and horrible GPS. No, I never rooted my phone, but you know what? You shouldn't have to root your phone just to make it work.
