Sadly of little use to me like all things not M$ Office.
Sadly this does not seem to work with *docx or even *.doc Template Files, which I need in order to keep my School Logs up to date. Google docs as pretty much all the other 'alternative' Programs share this trait unfortunately.
I have yet to find anything other then M$Office (beit 2003, 2007 or 2010 of which I use 2003!), to do so. No not even Microsofts HTML version of Office Live will allow me to edit such files, it instead sends me to a Site where I can buy there broken version of Office 2010.
If I knew that it would do so I'd might be tempted to get an el-cheepo W7P to take care of this chore, but I suspect that this task would also fail there.
As for making those HATEFUL Powerpoint presentations, of which I had to make a few. Why would I waste my time on this, and not say on my Netbook, which has the Keyboard and an actually readable Screen?
