There have also been concerns about storage capacity, with one writer estimating that the device will “only” be able to store 1,872 tracks, or about 150 albums, which seems sufficient to me, especially since the device easily connects to a computer to swap tracks back and forth. Although the soon to be released Pono Music Center app will only be available for Windows and Mac, Linux users will be able to “sideload” the player as a USB storage device and swap tracks using a file manager.
