In the days of ActiveSync (which means before I upgraded to Vista), I could connect my mobile device to my laptop, and copy files across from one device to another. This hasn’t changed.
But ActiveSync didn’t just COPY the files. It would CONVERT them as well (something WMDC doesn’t do). ActiveSync would convert Pocket Word files to/from .doc files (a problem Nick Randolph has faced too), Pocket Excel files to/from .xls, and also tag PDF files so that my mobile device could view them in Reflow mode.
Like the Pocket Office formats (which are must more compact than the Office 2000 equivalents), Reflow mode is just so useful – but without the ability to tag the file, it makes reading PDFs on my mobile device a thing of the past.
