I guess ChineseClass101 uses a very recent version of Acrobat to make the PDF files because I couldn't read any of them yesterday with Acrobat reader 7 + 2008 chinese fonts. The update from Acrobat reader 7 to Acrobat reader 8 + 2009 chinese fonts was so annoying and the result so bad with my actual computer (I can't read the PDF with Firefox and some characters have missing parts) that I don't even want to try with my PDA. Sorry this PDA will never see any CC101 lessons.
Wow, I can directly copy and paste the text of this sort of PDF.
CC101 gets extra points for that and my PDA will, in fact, see the CC101 lessons (mostly the audio blog).
