Steve Jobs informed gathered journalists that the iPod touch is the most successful portable gaming platform, outselling both Nintendo and Sony portable gaming devices combined.

And the iPod touch has just received a redesign as it becomes a fourth generation device. Not only will it come with the newly announced iOS 4.1 (updating to iOS 4.2 in November), but it now also gets 960 x 640 pixel Retina Display from the iPhone 4, meaning it is going to be great for watching HD video captured from the camera.

The case is now slimmer and the inclusion of a front and rear camera means you'll be able to snap pictures and video on the move - perhaps even using the new HDR feature - as well as have FaceTime calls if such a thing tickles your fancy. Of course, you'll need to be connected to a Wi-Fi network.

Elsewhere you have the 30-pin dock connector, external speaker, 3.5mm headphone jack and volume controls as previously.

You'll also get access to all the App Store goodness, making the new iPod touch an even hotter prospect than the previous version.

The new iPod touch will cost £189 for the 8GB model, £249 for the 32GB model and £329 for the 64GB model.
