I don't know anyone other than attorneys who use WordPerfect. Just habit and a bit of ease of use. I've used both. There are other programs that easily integrate with Word just because of Microsoft language translators, voice recognition, dictionaries. WordPerfect is far superior.
Reveal codes is the clincher.
Formatting in general is easier and far more logical than Word. I'm getting tired of learning new software. I really need to win the lottery. I expect WordPerfect to be phased out and Word to be the norm since most normal people use it. I have used WordPerfect most of my legal career.
