It’s one thing to be able to just listen to your music when on the go and quite another to be able to watch a movie or your favorite TV show. Now I’m not talking about those portable TVs. I’m referring to a PMP (Personal Media Player). Being able to watch a movie while commuting is definitely aces in my book. It can be a bit odd having everyone around you staring over your shoulder but hey, you’ll get used to it. The Vision:W was a great addition to the portable video player family. But of course the question is, how does it stand up to the likes of the Cowon A2 or the PSP. Let's find out.
Form Factor
Let me start off with the Vision:W’s simply brilliant 4.2-inch wide aspect, high-resolution TFT LCD screen (16:9 aspect ratio) featuring up to 262K colors. With dimensions like 134 x 75 x 22 mm and weighing in at 276g, it may be a wee bit heavy to simply pocket it and walk around.
On the top of the player you’ll see the power slider switch. If slid to the right it also acts as the hold. Much like the Vision:M. To the right are the volume keys and the microphone. At the back is the battery, which can be removed if necessary. On the left hand side of the player is a slot for your camera's CF (Compact Flash) card. So this could, to a certain extent, be a photographer’s tool. The right hand side is where you’ll find 3.5mm earphone socket and under a flap, just below that are the AV out and DC charging sockets. 
At the side of the large display is the control panel that has the return key at the very top, followed by the sub menu key. Just below them is the 5 way navigation pad and the play / resume keys and finally the skip keys. This is exactly the way I prefer it, no touch screen. The only drawback being that you have to keep buttons pressed in order to navigate through a movie or track. What’s even better is the fact that there’s also no scroll pad that’s a bit over sensitive like the Vision:W.
this one seems to be better than ipod in battery life
