AT&T has basically killed the Atrix's laptop dock with its pricing. The dock will cost you at least another $500 no matter what you do. You can buy it alone for $500, or pay $300 and be tied to a $20 per month, two-year supplement on your Atrix service plan (this will cost you $540 in the end). The $20 supplement also gives you 4GB of data rather than 2GB, and tethering abilities for any other laptops you may have, but it's mandatory, and most people don't use more than 2GB of data a month anyway.
The problem is I already have a very nice Windows 7 netbook, the Samsung NF310. For about $400, it comes with a more powerful processor, tons of storage, and compatibility with Windows 7. The Atrix can't challenge that math.
I pressed an AT&T rep on why the dock is so expensive. The bottom line is that the carrier wants to charge dock users the same as laptop users, who also get charged a $20 supplement to connect to AT&T's network. Basically, AT&T doesn't want to change the game, so they're killing the Atrix's potential advantage.
