Advantages of Tilt GPRS/GSM processing...

Tilt claims that they can run python code on one of their GPRS/GSM communication chips but I don't have enough experience to know if there is a real advantage to this...

So I'm wondering if anyone has done this and what pro's and con's they have seen besides price?
Are there any scenarios that you cannot do with the Arduino which would require processing on the communication shield?

Much thanks!

Link?

How does being able to run python relate to price?
