Yes, it's fairly stable, we usually hear about random freezes ever so often which requires a reset, mine has frozen once In 8 months.
The main problems are just bugs present and lack of simple features like resume, auto shut down, sleep etc... The main problem I see is at random C3 selects whether the file / folder names scroll forwards or backwards, it does so at random and has been programed to do so, we don't know why. It's pretty well behaved overall but it's really a basic interface stripped down with bare essentials. There's a slight pop noise in-between tracks (imagine a record needle hitting a spec of dust) doesn't really bother anyone for most parts.
