Any idea what the 'pro upgrade' adds? Doesn't say on the page. Being a free app I wonder how restricted it is without the upgrade. Support for 80+ file types would require a lot of time invested, unless most of them are built into iOS or have a free library. (I'd bet text/RTF files, PDF and common image types are counted in the 80+)
Its pretty rare that a file converter does a decent job. ie if you want to know what a PDF really looks like... use Acrobat. If you just want a glimpse this might be ok.
