Convenience, thy name is Andnroid and Apple. Dilly. Dilly.
Using mobile devices for controlling functionality is one thing, using them for storage and serving is another.
Even if a iPad or Iphone had the greatest amount of HDD space, it still seems weired to me to have those devices doing the job better more capable hardware could do on higher levels. This improves access to them from various platforms inside and outside the LANas well.
Having lossless files is but one part of the equation. Having them eat up space on moble gizmos seems a stop gap measure at best. For now, perhaps. But only temporarily.
The wired method mentioned above is interesting albeit for expediency sake. I would ask folks to bring thumb drives or Discs, if they wish to hear something played thru my rig I don’t aready own or own in a particular HD format. Its easier that way and I also get some new files now and then, with their permission of course. Dilly. Dilly.
