The perks you get vary by carrier as well. AT&T's big deal is DirecTV integration, which lets you both watch live TV and remotely control your set-top from your phone. Sprint, meanwhile, has a new Galaxy Forever program that (much like iPhone Forever) lets you upgrade to a new device after you've made a year's worth of payments. T-Mobile is tossing in a year's worth of Netflix, and Verizon will give you 2GB of extra data per month if you activate your phone on Plan XL service. And as Samsung mentioned during its keynote, pre-order customers get a free Gear VR headset -- if you're willing to pay full price for an S7, you won't be hurting for bonuses.

Update: And Oculus is promising a VR content bundle. Contents vary by carrier, but it says it'll total a value of $50. Enough to get some sort of VR habit going.
