What about Microsoft Word?
I'll bite. What about it?
As a replacement for WordPad? I think of WordPad as an overgrown text
editor. If you use it for text editing purposes, replacing it with
Microsoft Word is enormous overkill.
On the other hand, if you think of WordPad as a word processor, be
aware that it has extremely primitive word processing capability, and
just barely, if at all, qualifies for that name. Anyone who considers
it a word processor would probably find that the capability of Word
(or any real word processor) to be *far* more than he needs, and there
too it will probably be overkill.
Replacing WordPad with something like Word or WordPerfect is like
replacing a Yugo with a Rolls Royce--probably much more than is
needed.
As I said, it's not possibile to give the OP an intelligent answer
unless he tells us how he uses WordPad and in what way he finds it
deficient.
