What's your minimum requirement speed?
I'm really not one for saying I need a minimun, however I do watch alot of videos and surf the web when I'm not near wifi in my office or at home...
I was one of the first people to jump on vzw's LTE network when the Thunderbolt was released a few years back, and ever since then I've been extremely spoiled. I HSPA on at&t last year for the iphone 4s, and even more recently Tmobile's HSPA+ for the nexus 4, and while not terrible, it was just such a difference compared to the speeds I'm seeing now with at&t's LTE network.
With it being 2013 and LTE getting more wide spread by the day, I just don't see myself going backwards and using HSPA or HSPA+ as primary source for data speeds when LTE is available to me right now. When Tmobile rolls out LTE in NYC, I will 100% give it a whirl.

I'm still amazed at those speeds! I think if I had Tmobile or a snail with a phone on it's back I'd be alright. With my little 3 MPS I get anything else is fast. I got like 16 on wifi and that's the highest I ever experience.
I have Verizon Quantum for wifi in my office and home and those speeds are up in the
50Mbps bracket on a daily basis.
So to be getting upwards of 40Mbps and better on at&t's LTE network it makes no sense for me to even consider going anywhere else right now.
