When you look at something like the device type report, you get 'unspecified'. Wouldn't it be nice to change 'unspecified' to 'desktop' (because that is what it is)??
Or change 'none' in your other reports to something like 'data doesn't pertain to this report' or something a bit more pithy (because we all know that 'none' just means that the data has nothing to do with the report)??
