iPod touch 4

With the recent refresh of Apple's iPod range, the iPod touch has undoubtedly asserted itself at the top of the tree. With the nano stripping down, there appears to be a hole in the middle of what was once Apple's MP3 player offering. The iPod touch is safe though and you can't help thinking that this is the one that Apple wants you to buy.

The business reasoning would be clear. All the hard work that has gone into refining the iOS interface is demonstrated here and Apple benefit not only from sales of music through the iTunes Store, but also their cut of app sales from the App Store, as well as movies. It works on the model of a little here, a little there, but most likely the iPod touch will be a continual trickle of income for Apple from the moment you buy it. 

Of course you might choose not to buy anything and only use free apps, but from that point of view, you are spoilt for choice. Some may say that the App Store is a closed shop, but it's well stocked. A pricy device it might be, starting at £189 for the 8GB version (a hike of £40 from last year) and rising to a staggering £329 for the 64GB (up £30), but you also get the best portable media player for your money.

Out of the box, the new iPod touch reflects the changes made recently to the iPhone 4, with a slimmer profile and the hint of a square design. The back is still stainless steel, with a slightly squarer profile than previously. The new touch is narrower overall and one of the changes has been to remove the way the casing wrapped around the edge in previous versions.

And we're not sure we like this change. Yes, to look at, the new iPod touch screen is now framed by only a thin silver border. This means that the edge is harder and less comfortable to hold. Whereas previous versions had a comfortable edge, the new iPod touch does not. Many, we suspect will use a cover, in which case this change will make little difference.

Otherwise the design remains more or less the same, with a single face button below the screen, a volume controller on the right-hand side and a standby button on the top. Again, the angular edges mean that these buttons now sit on a reverse slope, so they are more difficult to press than before. The inspiration behind this design is clear - minimalism. When looking at the face of the iPod touch you can't see these controls as they are now tucked away behind, but as a result, they are slightly less accessible.

Other points to note are the front-facing 640 x 480 pixel resolution camera above the screen and a camera in the rear corner, with a mic next to it. The resolution of this camera is undisclosed, and Apple didn't declare that it wasn't going to give you the same performance as the iPhone 4's camera when they unveiled the new model, but more on that later.

Across the bottom of the iPod touch we have the 3.5mm jack, dock connector and an external speaker.

Build quality is solid, as you'd expect and there is no doubting that the iPod touch is a very sexy device. It feels premium, it looks premium, but you'd demand that from the somewhat premium price that you pay for it. It now measures 111 x 58.9 x 7.2mm and weighs 101g.

Of course the most significant change from the previous iPod touch is the display. We didn’t hear previous iPod touch owners complaining about a lack of resolution, but this is a big step from 380 x 320 to a cracking 960 x 640 pixels. A lot has been said about this display from the iPhone 4 and you get all the benefits of the high pixel density here.

The result is that it can render incredibly fine text. You can head into a website and read the text where previously you'd have only seen fuzz. The limitation is no longer the screen so much as what your eyes pick out from the page. It's hugely impressive and a great step forward for mobile displays and we hope it will be a driver to pull the rest of the industry along with it.
