Thank you for your input! I did get the 6GB plan, yes. And because of a promotion when I signed up it is $120 for 4 lines. So what I have now costs the same as this new plan. Between binge on and data rollover I never come close to my monthly cap, and considering that the high speed tethering is kind of a lifeline with a toddler at restaurants and road trips (and binge on does apply to tethering if I do stream from the included services), I agree that I should probably stick to my fast tethering! Kind of disappointed that they limit the tethering speed...
