Not a bad deal I suppose. My bill is under $90 for 2 lines and we don't hit our current data cap (2GB/month with rollover data) so I wouldn't need to switch.
It's a little misleading though. The $115/mo for 2 lines is throttled to 3Mbps and includes mandatory StreamSaver which is something they just rolled out. It basically limits all streaming video to 480p on your phone. Not a bad idea really - do you really need 1080p youtube on your phone?
So if you want the real "unlimited" plan, you have to pay $145/mo for 2 lines.
Nothing is really unlimited and they are very clear about the terms even in the big font promo. Both plans will throttle after 22GB (reasonable) and I think only the more expensive plan allows tethering. And even then it is limited to 10GB before throttling. I think these terms are reasonable but the prices aren't going to set the world on fire.
