Got mine yesterday. Sucks that if you order online, the 3 day window of the activation fee sticking starts the day you order. So, today is officially day 3 for me. If I decide I don't like, I'm stuck unless I return it today.
So far, LOVE the interface. Very smooth and responsive. A little disappointed on the lack of apps, but I'm sure that will grow in time. I guess I was just trying to download as many of the same apps that I have on my Droid Bionic as a comparison.
Where I'm located in central Florida (Orlando) is listed as an HSPA+ network, but I gotta be honest that even when in downtown O-Town, 2.1 MB down is really disappointing when things are near instant on my Bionic. I'm spoiled, I'm not gonna lie.
I need the Titan on an LTE network and I think I'd be extremely happy. However, I'm going to continue to evaluate since today is my first full day with it.
