...WordPad? I can't even find that. (OK, on accessories -- but there is a reason it is called accessories). Travis, forgive me, but I can't use RAM as an excuse. And, I certainly don't feel sorry for anyone who doesn't have an Office Suite on their PC whether it is Microsoft Office or Open Office. (Free)
To say that we shouldn't use Word, because some people don't have it, would be akin to saying that the program doesn't need to print because some people don't have printers.
The whole idea is that it will open in whatever editor you have. If not Word, then it likely would open in WordPad.
The letter writer is embarrassing. There are users that have left AC over the letter writer. Why should we have PDF. We can just convert a word document to HTML or Notepad.
WordPad is actually a decent alternative. You can make a pretty decent letter in it. It is essentially an stripped down version of Microsoft Word. And everyone has it. It's better in Windows 7 than XP, but that may be an excuse to move up in the world.
One issue is the ability to "lock" the letter. For medical legal reasons, it is a good idea to do this.
Could it be saved as a template, automatically in WordPad if that were the new default? (Apparently it is not an option directly, but Open Office xml is an option (and I do not have OO on my laptop) but it might have to ability to be added.)
I, for one, still prefer LibreOffice (Open Office's better incarnation) but WordPad may be an easier universal solution.
