The above is the MP4 player which Chinavision is at the moment claiming to be the world’s thinnest at just 4.5mm thick. Yes, that’s less than half a cm in length if you take out your ruler! Though there isn’t any info on its weight, which I suspect wouldn’t be too much, the 4GB CVSJ-1304 has a 1.8 inch touch screen that boosts a resolution of 160 x 128 and supports media formats MP4, MP3, WMA, ASF, and WAV. Other features also include FM tuner, rechargeable battery and USB connectivity. It’s hard to believe but it’s already on sale for just $39.95, which is round about 20 quid and it seems if you buy more you get an even cheaper deal!
