As well as promising "clean, crisp sound" for £69, the i-Station25 from Logic3 has built-in accelerometers so that you can use it vertically or horizontally.

This means you can watch video content landscape, but the accelerometers will then automatically adjust the speaker output to maintain the correct left/right adio separation.

Logic3 claims that this cuts down on noise distortion.

Also worth a mention is the fact that the speaker dock has a video out function for the iPhone, iPhone 3G, iPod Nano 3G and 4G, iPod classic and the iPod Touch 1G and 2G, and also stereo line-in.

You also get a remote control, and can power the i-Station25 either using four AA batteries or using an AC adaptor.

It is available this month on the high street.
