Why would anyone bother tethering, if the data plan is capped.
For me, the allure of tethering is the possibility of not needing to pay for an air card. But if the data plan is capped, I'd be maxing it out all the time because my laptop is on almost 24/7 with VPN's and everything. So fuck that. I'll just keep my air card, and forget about tethering.
Oh and as for the iPad, fuck that, it's just a big iTouch
Fuck ATT too. Verizon all the way. But no, they'll never have an iPhone (and who cares anyway).
