Speak Mandarin in 500 Words

This morning thanks to random surfing I found yet another beginner textbook: "Speak Mandarin in 500 Words".  It is available free thanks to the Taiwanese Overseas Chinese Affairs Commission. As you might expect, it is aimed at folks who desire to learn Taiwanese Chinese (Traditional Characters using bopomofo phonetics) however it also has pinyin. And for added bonus the book has French, Portuguese, German, Spanish, Thai and Indonesian editions in addition to English. And for even more added bonus, you can get the (PDF format) text book with embedded audio for the lesson dialogues. (Who knew that you could embed audio in PDF! However, at least on OSX, you will need Adobe Reader in order to hear the embedded audio - Preview does not handle sound in PDFs) In any case, this textbook seems to be very well crafted and very suitable for a beginner and hey its free.  Here is a (slow) link
