My 2nd Zaurus arrived yesterday. Audio quality is good and the MP3 player works. Now, I can finally get down to business on the very important task of ripping my MP3 collection for my commute to school.
In short, I was upset that the first one didn't work. But, I was happy that the on-line vendor accepted my return and sent me a new one, although it did take approximately 2 weeks and I had to pay for return shipping. I guess that's what you get for bargain hunting.
