The quick office update really makes a big difference. I have box.net, dropbox, and google docs all connected via the touchpad. Its easy to move files between them including the touchpad itself. This function elevates the TP to a serious contender for my primary workhorse. As a pre- user I'm used to transferring files the hard way via emails and a combo of evernote/gdocs using copy/paste.
I'm sure other OS have enjoyed this but for the webOS folks this is awesome.
you would think HP would have highlighted this function more.
