The problem is that there is no progress bar while syncing, you don't know when Ubuntu is done syncing the files, thus there may be a loss of data when you unplug your usb device too early while it syncs in the background.
In the operating system of a company headquartered in Redmond they automatically sync while copying the files and show a correct progress bar. Maybe something similar to that would be better in Ubuntu.
