I had two vibrants - one lasted 15 days, the 2nd 45 days - (tmo extended my remorse period over the gps issue). I had rooted and installed one of the lag fixes - and i thought that vibrant was fast, until i got this G2
i don't want to say the G2 blazes past the vibrant in blinding speed fashion, but it is definitely quicker and smooth as silk in all functions
i haven't noticed any tint to the screen - i don't think the screen or display is as brilliant (colorwise) but it's definitely nice
size on the G2, dropping to 3.7" display, i was worried i'd miss that display size. Nope - the size is perfect, both visually and size is perfect in my hand (i'm 6' w/large hands).
only "fault" i have with the G2 vs the vibrant - the speakerphone is definitely not as loud, and when set to max volume, the sound breaks up - i suspect it's because the speaker is right behind that metal backing cover - and it's reflecting that sound - when i put my finger on the metal cover there, the sound improves, and same if i remove the back cover. But that's a minor minor "issue", nothing i'm worried about.
oh, the GPS - IS FLAWLESS - even shows me moving around in my house, and is always oriented correctly to the direction i'm facing. Granted my house is 88' long, but it shows me moving around inside my house, from one end to the other.
i did have some concerns i'd miss the vibrant, i liked it that much. But that's not the case.
now i'm just looking forward to someone rooting this phone, so i can ditch some of the bloatware.
