Honestly, mostly for fun and love of Rockbox, I've wanted it on my desktop since 2010 and nobody else was going to build it :)
That said, Rockbox does bring real things: a battle-tested DSP chain (crossfeed, EQ, replaygain, dithering), gapless playback that actually works everywhere, codec coverage most players have given up on (Musepack, WavPack, ...). It's a lot of mature work to throw away.
