I have about 100 albums on my little DAP and it isn’t as bad as you’re probably thinking. If I had thousands of albums, yeah, that would be a no go, but I really don’t want to be text searching on my music player generally. As long as it has filter menus for artist and genre and the UI isn’t totally brain dead it is likely fine.
I switched to using a dedicated DAP because I haven’t been able to get a phone that fits my needs with a headphone jack. am considering getting this, if the kickstarter was active I’d be tempted to get it at the $75 price. There’s no way I’d pay over $100 though, there are too many caveats I have with this device considering I already have a DAP that is OK.
Other con: Unless you have a new home with pristine wires, the speeds of MoCa can vary anywhere from 2.5Gpbs to 6Mps. It also gets very tricky if you have still cable TV in your home because many of the set top boxes use MoCa and they directly interfere with using it for internet (though you can sometimes get it working with filters, my experience was poor). MoCa is still far better than something like Powerline adapters, which are another option for not having to run new cables/lines.
