For the most part, though, you'd only notice the YP-R1's 'problems' if you've become used to the nuances of another touch-driven UI, such as that on the iPod touch and iPhone which is still significantly better than that of the YP-R1. In isolation, there's little to complain about though and the occasional gem can be found.
My favourite is the Bluetooth screen which shows available devices circling around, which you then drag to the central YP-R1 icon to start pairing. It's gimmicky, sure, but it's also undeniably cool. Having long file names scroll across the screen on a press and hold is pretty inspired, too. Finally, if you're like me and prefer a list to a slideshow parade of cover art when browsing music then the File Browser will be a regular port of call.
The presence of a voice recorder and FM radio won't surprise anyone, given how many other features have been crammed into the YP-R1. Both of these work well enough, although I doubt anyone would actually have noticed their omission. Samsung claims the YP-R1 will cope with 30 hours of audio or five hours of video playback. Both of those estimates are pretty much spot on, until you start playing around with Bluetooth which drains battery life like it's going out of fashion.
Format support is comprehensive. On the audio side MP3, WMA, Ogg, AAC, FLAC, WAV and ASF files are all playable as are DivX, XivD, MPEG4, WMV, H.264, ASF and RMVB videos - as long as the resolution is kept to 720 x 480 pixels or below. If it takes your fancy, the YP-R1 will display JPEG, GIF, BMP and PNG images, too.
While DivX support might seem a little superfluous on such a small player it's actually pretty useful. Not having to re-encode all of those… um… home videos in order to put them on your portable player is a real time saver. Plus the screen on the YP-R1 is remarkably capable, producing deep blacks, vibrant colours and fluid motion. It's definitely the best screen I've ever seen on this size of player.
