My org is just me. My revenue has remained fairly flat over that period. But the cost to access my data has risen rather steeply over that period. Had I purchased a stand alone application to start with, I would have saved 50% of the cost.
I'm not talking about large installs for big organizations - I was speaking directly to the value options for small organizations. Most SaaS are designed to funnel end customers into higher profit services for no real reason other then higher profit. Value wise it's not a good deal for the customer.
