I don't have a padfone should I get one? topic

Hi,
thank you for clicking on my link and hopefully writing a response.
I have 3 questions I hope you will answer question 3 at least.
Background:
I have a asus tf101 transformer and love it with its custom rom.
I have an Asus router and love it.
I have a note 3. I held off getting note 4 because I expected at the point to have a Google project ara Lego phone in my hands.

The problem
I use sprint. I'm with my employees at remote locations usually with no wifi in the middle of the building where we are at.
They have att or t-mobile. No one has Verizon here longer than a week as their coverage is just that bad.
I usually about 97 percent of the time have a usable signal were they do not have any signal with t-mobile or att.
1) Does the padfone x have band support for sprint?
2) Is there a rumor site for an upcoming 2015/2016 release of the next padfone?
3) are you happy you got your padfone? If yes what make/model and rom are you using?

Once again if you can only answer question 3 I'd love to hear from you!
