I like that it is very easy for users who have no background knowledge about statistics or programming languages but just want this tool as an additional feature to their existing systems. It's not perfect yet so we need more improvements from developers side before going live again. The best thing would be if they can add some new features such as prediction charts which will help us see how our future predictions might turn out. We use tada mainly because its free version has all necessary functions needed at present time without any limitations regarding size/volume etc.
