I meant that in Windows there is an alternative to attachments to an extent. COM allows an application to embed in another application. i.e. I can paste some Excel into Outlook and it will keep the table formatting and I can manipulate it in Outlook as if it were Excel. It's not the best implementation though (pretty bad on the other side), and there probably is a much nicer way to do it. You could be right, with a better implementation there would be more that choose to work that way. I still think the risk outweighs the possible limited benefit though.
