Unless you plan to plug in a mouse and keyboard, I wouldn't recommend the Radius for getting a lot of work done. (The downward-firing drivers sound okay on a desk, too, but they'll get muffled if you place the machine on your lap.) Between the screen and speakers, I'd definitely recommend the Radius 12 for watching movies and TV shows. While the integrated Harman/Kardon speakers don't have a lot of bass, they sound remarkably full and loud - particularly in tablet mode, where they create something of a sound chamber when you fold the lid against the frame. Surprisingly, Toshiba managed to deliver decent audio quality in a laptop this thin. There's not a lot of 4K content to watch, particularly on computers where big companies like Netflix and Amazon refuse to stream their 4K content, and many Windows programs haven't been updated to look good on 4K screens. Also, keep in mind that 4K isn't all that useful.
