It was only a matter of time - dual-core droids are getting cheaper. The Motorola Atrix 4G has dropped to $99.99 on AT&T with a 2-year contract, down from the $199.99 that they originally asked for it.
You can snatch an Atrix 4G from AT&T now but there are two things you need to consider - you need a data plan (starting at $15/month) and you really should look at the docks.
The HD Multimedia dock for the Motorola Atrix 4G can be had for $129.99 and the premium laptop dock costs $199.99 (after a $100 mail-in rebate). Unfortunately, those are the prices for buying either dock separately - no discount here.
Interested? Then head over to AT&T's online store.
