I have a TF101 epad Transformer & they were horrible about updating it. it shipped with android 3.0 & there were a few updates but Asus never updated it to 4.0. They just left us in the dust. We should be upgraded to marshmallow though.
I ended up having to get C model shipped from Best Buy because it was not available in the store. Could justify the extra cost for the CA model on an android device. Does anyone know if the stylus is compatible with the C model?
