No question on the C90 superiority. Great improvement on the 9500 which had a blatant design fault with its hinges, and a very inferior camera. Nevertheless, The C90 is very expensive and its features will be lost on the masses. The down side of this phone is the GPS system which I feel is a waste of time. I would rather invest in dedicated GPS systen than struggle with the C90. I dumped a lot of text files on the phone to find that the C90 will allow you to read the file but will not allow you to edit. Hence you cannot copy from a text file and paste into you SMS or email whatever. (The 9500 allowed editing) The beauty of the C90 is that you can access all its facilities from the front screen without having to open the phone and using the large screen, whcih saves a lot of battery power. I think the C90 is a top-class instrument. I had good use out of the 9500 and as I see it, I will have very good use out of the C90.
