What is a good Pen PDF application?

thinkpad-stylusI haven’t found a good pen PDF application for android or Windows.  I don’t have an iPad so I don’t know about pen pdf apps on it.  What I mean by a pen PDF is being able to use a stylus to write directly on a PDF and have it save.  First, the adobe reader app for android does do this.  However, the stylus I use has a fat rubber head and I am not sure I will get the lines thin enough with a more pen-like stylus.  I need more accuracy to fill out entries on a pdf.

PDF apps on my Thinkpad 2 tablet are not very good either.  I have tried 3 of them thus far and they have all sucked.  Adobe reader doesn’t support stylus, foxit shows that it can do it but I couldn’t get my stylus or finger to draw anything and the other program I downloaded I can’t even remember it’s name now.

Lastly, Windows built in PDF Reader happens to work the best if I can even use that word.  First, there is no undo, Second, it is lagging and lastly, writing on the table while it is in vertical mode is a waste of time.  It is virtually useless.   You might think that all I would need to do is to turn it back to landscape then, well, at least this tablet has a very difficult time rotating.  For some reason it just won’t rotate if I am looking at a PDF.  Sometimes it doesn’t rotate even if I am in the desktop!

I work about once a week doing independent contractor work at different sites.  As you can expect I have lots of paperwork to fill out.  Instead of wasting the ink and paper to print and bring with I much prefer to have it all in my tablet.  Even if it was printed on paper I would be scanning and emailing the document once I was through with it.  From what I can tell there may be some excellent apps on the iPad that would do what I am looking for.  Unfortunately, I can’t justify the cost of an iPad for just one purpose. Believe me when I say just 1 purpose because I can’t stand how the iPad is locked down.

I am going to keep on searching but I hope I can figure out a solution to this.
