I disagree.. PDF on Nokia n900 is great for reading long texts. Personal taste I suppose.
I also think line wrapping is not necessay. if you cannot read a PDF document on 100 percent on the Nokia N900, you either need to use your glasses or curse the idiot who created the PDF with an abnormally small font.
All PDF that is readable on a computer screen is also readable on normal 100 percent zoom on N900 standard pdf reader.
