I use the TF to do lots of typing, between classes and paper work for my business it its a necessity. Our also makes watching movies and stuff nice cause you dont have to hold it. Those are the convenience uses.
But don't forget that the dock also provides you with 2 usb 2.0 slots, great for the 1tb portable hard drive, plus an additional full size sd slot. If that wasn't enough, asus felt they also need to add a set of batteries that increase life by about 6 hours. The nice thing about it is that if your tf is not 100% charged the battery power will transfer to the tf until it is, essential making the dock a portable charger as well.
I can't speak more highly of this tab and dock, to think,i was intending on buying a galaxy tab but it was sold out so I bought the asus on an impulse... Sure am glad I did!
