Great question. If I remember I'll reply somewhere in a month, I'll try to go past the 15GB mark by then. Opting out of the cap would make this useless for me.

Great question. If I remember I'll reply somewhere in a month, I'll try to go past the 15GB mark by then. Opting out of the cap would make this useless for me. But if you were reimbursed by an employer upto $X and that's what you want to spend, not going to normal speed starts to make sense.
