i do not know ho this device works, all i had thus far is a rockboxed ipod video 240GB , the way i browse is geners> then i have everything sorted by artists. if this is possible with the DX90 its great.
but still i do not know how it reacts to card swapping, does it have to build database like rockboxed ipod? which by the way takes some time to do... or is it instant?
P.S highest capacity SD cards in sane price right now is 128GB? the 256 i saw so far were fake/overpriced.
