With just a 2.6-inch screen to work with, watching videos is never going to be a particularly immersive experience, so we didn't expect too much. The 320 x 400 screen makes it a little difficult, too.
Watching movies full-screen cuts off too much of the picture, and watching them in their native 21:9 widescreen format means less than half the screen is filled by the video. 1080p movie trailers look reasonable good on the device, and the footage is clear and crisp, but you really have to strain to see any detail.
Speakers sound relatively good, but very, very quiet. The video player itself is nicely designed and simple, but you'll often find that simply touching the screen during play means it'll skip though the video. Annoying.
The YouTube application, using the same player, is great, though, with fast loading times on 3G and Wi-Fi.
In terms of music, like everything on web OS, it's nicely designed, easy to use and logical. It has a Cover Flow-like system allowing you to easily choose your favourite tracks.
Also, you can minimise the application and still control the music, thanks to the mini-player housed in the bottom-right corner.
Adding music is easy, just drag and drop from your computer, and it will play MP3 and AAC files, but web OS is really lacking a music download portal, because the promised Amazon MP3 app still hasn't arrived in the UK.
You can download directly from the site however, but that's a massive hassle. Again the speakers are a little too quiet, but the bundled-in headphones are better than they look.
You will need some decent cans, however, to get the best out of this device.
