I am not necessarily unhappy with my purchase but I am certainly frustrated. There are so many small changes that I keep experiencing without any real feel for how it affects what I am doing. Far too many assumptions are made that the customer is computer savvy and will know what to do. I am a self-taught non technical user and find it difficult to know how to perform the tasks I want to do. Without any manual at all or even a list of possibilities I am under utilizing my 8.5 and wishing I could go back to what I had before. Updates and changes often catch me by surprise and I have to call my daughter in Chicago for answers.
