Flexibility is its strength. I wanted to create a file with a value list that could be edited. It worked on my Mac but did not work on my iPad mini. So I replaced that feature with a table with one text field. It was actually better than using a value list.
Now when I observe student teachers, I can write a review, get a signature and file the report before leaving the building. It gets better than that: I can include pictures of the student teacher teaching or student work with the report.
A couple of comments on other reviews:
I was able to email several pdf files in one letter; I have had no problem with a portal on a layout.
