Re: Pono Player
You raise a good point about the shape allowing it to be used easily on a desk. However, this image of the internals suggests it could be made slightly more pocket-friendly:
>I can probably get a Moto G or cheap Nokia Lumia for £100 - and put a 128GB SD card in that.
For large audio files, or for lots of normal audio files? A word to the wise: They can't play back 192Khz FLAC files natively (though the LG G2 can). If you want a 128GB card in order to have tens of thousands of normal audio tracks, you might want to read up on Android file limits and FAT formatting etc before you make any purchases. Just in case there's a niggly issue.
If you want 128GB for losslessly-compressed CD-rips, ignore me!
You might also consider a spefic version of an older Samsung Galaxy model from eBay, since they are said to have Wolfson DACs. Apparently.
