I am seriously considering buying a 'new iPad'.
Apart from the usual music, movies, browsing etc I also want to use it for a specific business application :
I have moved into a new job role and the biggest part of my learning curve is learning all what has gone on in the past - especially the correspondence between ourselves, major vendor, partners and government authorities.
All the historical correspondence (1 page to 30 page pdf files) are available, sorted in folders / subfolders by country / project / company etc on my PC.
There are probably around 50 folders containing 900 files in total (500MB).
I have trialled pulling all the pdf files from one specific folder into iTunes (Add File to Library function) which worked successfully.
In iTunes, the 'Book' name is the file name and I can edit Author/Artist to a specific originator (company); Grouping to a specific project; Category/Genre to a specific country.
I then synced Books between my iPod Touch and PC. Using the iBooks app I have access to all the pdf files but when looking at the 'Library Bookshelf' I lose all the filename / Author/Artist, Grouping, Category/Genre so they are all pretty random.
What I need to know is what is the best app for the functions that I need :
1. manage the pdf files into a structure of folders / subfolders etc with visibility on the file names
2. open and read the pdf files with reasonably good refresh and page switching rate
3. allow me the minimum of file annotation - either highlighting or underlining sections - I would even be willing to forego this if 1 and 2 were covered.
I've read most of the threads which recommend GoodReader, iAnnotate, PDF Reader and others but they seem more applicable for books or a much smaller number of documents.
Any suggestions much appreciated.
