What do you like best?
Text Edit plus has exactly all the features I need, and nothing more. It expands slightly on the OS X default Text Edit standard, but doesn't come with the price tag of Microsoft Word. Text Edit Plus loads quickly, has all of my basic formatting options, and maintains a very clean UI.
What do you dislike?
Working with scripts in Text Edit Plus requires a little getting used to as far as what commands Text Edit will understand and implement, but once you adjust to what you can and cannot do with scripts the program is easy to use quickly.
Recommendations to others considering the product
If you find that you aren't using the more complicated features in MS Word or Pages, but Text Edit standard is too simple for your needs, try using Text Edit Plus to fill in the gap in the middle of those pieces of software.
What business problems are you solving with the product? What benefits have you realized?
Text Edit Plus saved us money because we did not need the full feature set of MS Word, and now we don't have to worry about paying for MS Office upgrades or subscriptions.
