After viewing videos of the docks that the ATRIX 4G can connect with, you might want to consider a package deal consisting of the Motorola ATRIX 4G and the laptop dock for $499.99 which is after a $100 mail-in rebate and a signed pact. Without the phone, the laptop dock is priced at $499.99. so if you are even considering it, buying the phone together with that dock is obviously the best way to go.
Motorola is also offering an Entertainment Access kit for $199.99 which includes a HD Multimedia dock, Bluetooth keyboard and a mouse. The carrier is not offering a bundled plan with the Entertainment kit. And to pre-order the ATRIX 4G, your AT&T plan must cost you a minimum of $15 per month for data.
