I've only had it since Christmas but I'm really liking my
K5. Not only does it look good but it couldn't be easier to use. The interface is so intuitive that I didn't notice that a paper manual wasn't included (although there is a manual in pdf format on the included disc). Adding songs are as simple as dragging and dropping and it syncs up with a number of programs. While the player is a bit thicker than an Ipod - the speakers are certainly worth the bulge. While the sound isn't loud enough to blow your pants off it'll certainly fill a moderately sized room - all ranges of music and a surprising amount of bass. The speakers provide the sort of sound that'd put most laptops included with high-priced name brand speakers to shame. You get an admirable 30 hours of battery life using the (most comfortable and best sounding headphones I've used) headphones and about 6 hours using the speaker.
The K5 also includes a built in FM tuner and the ability to view pictures (while you listen to music) and an alarm clock that you can set to whichever songs you'd like.

I'm only a few weeks in to owning it and I couldn't write enough about it.
