I was lead to believe that if I connected the iPad to BOTH profiles on the computer, it would in essence merge the data; thus the question...
I don't have an iPad, but I believe that if you're connecting to a Windows PC
and the profiles are set to not share music data, such as what's in iTunes,
then they shouldn't merge. In other words, if the different profiles have
different iTunes data already, then the iPad will sync according to what
profile it's on. I don't think it would merge the data if you wanted it to. I'm
almost sure this applies to the iPad just like the iPod/iPhones.
It might be easier to let the two profiles just share iTunes as a whole. That
way you can merge everything with no problem.
