Once the tiered data plan is in effect, I hope our byte counting overlords will not charge for tethering and no bandwidth throttling unless you are over your allotted data limit.
It's really not that simple. For any given plan, the ability to tether will result in higher usage. Maybe not that much if caps are low enough people still need home broadband. But my data usage on my phone is mainly spontaneous or necessary out and about. If I could tether, then I'd tether my laptop while surfing. I'd tether to watch that Netflix movie on a larger screen rather than the Droid.
VZW is charging $30 for mobile data for your PHONE. 5gig mobile broadband plans are $50. So if they cap at 5gigs, to include tethering they would likely charge $50 (or, more accurately, they will not include tethering and it will be $20 extra).
VZW prices are competitive. They are not going to give something away they currently make money on. All these threads complaining show demand is quite high, so don't expect any handouts.
I would absolutely prefer 5gigs for $30 with no tethering than 2-3gigs for $30 with tethering.
The bottom line is this: The 4 major carriers all charge @$50 for 5gigs of mobile broadband data. Anyone wanting any realistic amount of data for their phone, PLUS tether, should expect prices to be @$50 for such a service.
