Pros: none that I know of
Cons: crashed during scanning operation, does not appear to handle merging multiple pages into one document, at least not intuitively
Other Thoughts: Well, the only thing I wanted this for, was to scan pages from my pager, and merge them into one document.
The scanning operation ran (slowly), but when it was done the scanning page was simply frozen, could not interact with it at all, I had to kill it with Windows tools.
So I scanned the pages with some other program, then tried to use PDF24 Creator to merge them into one PDF file. I tried multiple options within the program, none of them ever succeeded.
This *might* be a good PDF editor, I don't know, but for the operations that I wanted, it was just useless.
Fortunately, Ultra PDF Merge worked fine for me.
