I have the option right now. It's called HotSpot on my iPhone.
No need for an expensive add-on that locks me into a single carrier. If I want to switch carriers, then I simply use the tethering option of my new phone.
Carrier lock-in is not just a US thing. Looking at 3G options on Dells, I have to choose a specific carrier and pay extra for the priviledge. Carriers give away the 3G USB modems and most phones support tethering out of the box.
Not to mention Apple would not make it BTO.
And the post you were responding to also didn't really list anything that required Sandy Bridge. Making it entirely moot and addressed by own post if you had bothered to read it entirely.
You can twist the argument any way you want to, it doesn't really matter. I quoted the post in its entirety and responded to it as such. Get over yourself.
