We have to wait for somebody else to confirm your question, I wrote what was quoted.
PDF reading is not perfect. Text is readable, internal documents links function, but small page size results in lines being wrapped where they are on one line in the original.
This is particularly apparent when viewing tables of data, such as Financial Statements. The table is displayed as a column, making it very difficult to read.
Unfortunatly, MobiPocket using the media card, prevents me from making screen captures to document the display differences.
