Best word processing app without a sync feature?

Question

Hi there.  My Grandpa received an iPad for his birthday for use while working on the job.  Here is an explanation of the situation:
My Grandpa goes into paper mills and checks their machinery to make sure they are working properly.  His traditional way to document this was by hand, writing out data into a checklist every week.  Then, my Grandma would later re-type all of this data into Microsoft Word documents their computer.  We figured the iPad could help save my grandparents a lot of time if used in place of this system. For one, files could be transferred over to their computer from the iPad, eliminating the need for entering the data by hand into the computer.  Second, instead of rewriting out a new checklist every week, my Grandpa could simply open, edit, and re-save the file from the previous week while on the job, since much of the data rarely ever changes.
We eventually got a system set up but we have had a few difficulties in the process.  Since the iPad doesn't support an actual Microsoft Word app, we knew we had to find another app that could open and save Word files.  We first tried iWork Pages for iPad.  The problem with this app is that files can't be saved by hand.  They are automatically saved by Pages.  This eliminated the use of the 'save as' option, where my Grandpa could edit a previous file and 'save as' with a new name.  Pages also had trouble formatting documents previously made on my grandparents' PC.  By the time the documents were transferred back to the computer, the formatting was messed up and it was not worth spending the time to correct this problem.  Their current app is Documents To Go, which has worked a lot better.  There is both a 'save' and 'save as' option, and document formatting is kept the same on both the computer and the iPad.  However, we've run into one main problem with Documents To Go, and that is the Syncing feature.
I've never been a big fan of syncing myself, simply because it's really easy to make a mistake and not be able to fix it.  It is 'convenient', but you have very little control the process.  I much prefer a drag and drop process because it allows you to know exactly what's going on during your file transfer because everything is being done by hand.  Syncing works fine if you know how to use it.  Unfortunately, my Grandpa is not a very tech savvy person, but he was more than willing to learn the basics of the iPad if it could help him with his work.  The main thing he has trouble with in word processing is the difference between 'save' and 'save as'.  Since he is always opening up files from previous weeks to edit them and save them as a new file, it is critical that he uses 'save as' in order to give the document a new name.  However, sometimes he forgets, and clicks 'save' instead.  This overwrites the old file on the iPad.  This would not be that big of a deal, except for the sync feature.  Since my Grandma always syncs the documents each time my Grandpa comes home from work, the new files are synced to the computer.  However, since the sync is a two-way system, any changes made on the iPad are transferred to the corresponding document on the computer.  So if my Grandpa accidentally hits 'save' instead of 'save as' on the iPad and overwrites the previous week's data, the corresponding file with the same name is also overwritten on the computer, and therefore, all data from the previous week is lost.  This would not be so with a drag and drop system, where a pop-up would notify my Grandma that two files have the same name, and she could rename the newest one accordingly, without losing any data. 
So basically, I need to find a word processing app that uses a drag and drop system rather than a syncing system in order to simplify the process for my grandparents.  The app also needs to be capable of keeping the document formatting the same in the transfer process, as well as have 'save' and 'save as' options.  I know there are other apps out there, but there no trial versions, which means to test each one out, we have to purchase them, and we have gone through two purchased apps already. 
If anyone out there has any advice on what we should do, we would very much appreciate your help on this issue.  Thank you.

Word is not that incompatible.   But I do recommend looking at this listing of alternative products:

The real problem people face with Word are font conflicts with some applications, macros that can cause files to misbehave, and using a version that hasn't been updated for their operating system.  Version 2008 and 2011 are able to run on the latest operating systems, though some people have mentioned the installers have trouble on version 2008 on Mac OS X 10.7 and later.
