Most of us in this particular forum is going to be pretty biased, including me, but I'll give you my two cents.
The E4GT is a superior device to most, not all, but most and you wouldn't second guess your desicion after you have used it for a while. I can't honestly speak for the hero itself but HTC left me pulling my teeth out using the Evo3D inwhich I ultimatley traded in for the E4GT. To be honest, I couldn't be happier.
Yeah, the E4GT is a little slick to touch but a seidio active case remedied that problem real quick for me. As for the hero, I have never held one let alone even used it so my opinion is soley biased but from what I have heard....the hero lost it's powers and was banished to the island the iphone created....anywho...
Do me a favor though....through that instinct in the toilet and forget about it. I had the instinct 24 hours and I would have rather stuck a spork in my eye.....
You do know though that the Nexus 4G/LTE is coming to Sprint right? You might want to hold off till then....just a thought......Good Luck!
