I love this feature, and am not looking forward to 2015 (or so) when my employer finally gets on OL2010. (We just upgraded to OL2003 at work!)

I regularly get spreadsheets from people, and often, those spreadsheets are not set to print properly "out of the box". Either the print area has been set to be too large, or they hardcoded the scaling percentages rather than setting the number of pages, or they had the active worksheet set to a blank sheet -- all of these prevent me from printing the file directly from Outlook, so I'll update the spreadsheet and save it back to the message for archiving.

Adding the "Save As" and delete/reattach steps needlessly adds extra time to this process.
