Too be honest, it's a bit of a gimmick I have found - it's soooo slooow as it runs on TMobile and their 3G coverage seems pretty poor.
I wish I could tether it off my HSPA EE mobile connection to make it usable but this is not possible once the BMW Assist is activated.
Also, any kind of text entry is rather painful with the iDrive controller.
So, in my opinion it's not really a useful addition to the car but as it's quite cheap it'll help sell the car on at a later date as it sounds rather fancy.
