@kettch:I don't know that we feel the need to 'justify' it, but yes, clearly we have our reasons, and have made what we believe to be a commercial decision. I would hope that the majority of business does the same thing - compares the cost of upgrading with any commercial benefits it offers them - and then makes a choice on that basis. We ran trials using a cross-section of our usage, task workers, admin, tech and management staff, and failed to find any compelling business case to at least offset the costs of upgrading. I'm in no way suggesting that our case is emblematic of all business, but I am comfortable that we made our decision for the right reasons.
