With some other DAP makers making players with a card slot and no built in storage for songs, I am wondering why Sandisk doesn’t make any of these? I’m talking about high quality players with a nice display, and large database for songs. Using an easily swappable inexpensive Lion battery such as the 18650 would be great. That way the player can be without any usb connectivity at all. Batteries would be charged outside the player, and firmware updates would be placed in the root of a card, then inserted into the player. Saving the size and cost of usb connectivity and charging circuitry would leave more space for a larger battery, and a larger budget for better quality components. How about it? I would love to see one from Sandisk under $100
with two card slots, a large song database(at least 20,000 songs) that uses an easy swappable high capacity battery, gets over 50 hours of battery life, and has high power output(perhaps at least 70 mw into 32 ohms).
