I'm thinking about getting a new mp3 player and I seen this thing. I like that it is a small size, but I'm wondering how the sound quality is and what kind of memory cards it needs. I have seen they now make 128GB cards, but not the micro ones. Can it use a normal size memory card? I think the 128 is just a regular SD card. Biggest I've seen in the microSD is 64. I'm just wondering if someone can answer these questions and give me a review on it. I understand it can be Rockboxed too which is good since I have a lot of Apple Lossless files I want to be able to play on it. Thanks.
