Yeah, that's what I'm probably going to end up doing, but it would be nice to just have the data available in SC or DW as it exists in the raw data. Also, the browser needs to execute JS to capture the data in an eVar.
Please make the user agent string avaialble (like IP address is currently) in Data Warehouse so it can be used to identify bots that are not included with the new Bot filtering rules under SC15.3.
