The iTunes Store is an online media store run by Apple and accessed via iTunes. It was introduced on 29 April 2003 and it sells individual songs, with typical prices being US $0.99, AU $1.69 (inc. GST), NZ $1.79 (inc. GST), €0.99 (inc. VAT), or £0.79 (inc. VAT) per song. Since no other portable player supports the DRM used, only iPods can play protected content from the iTunes Store. The store became the market leader soon after its launch and Apple announced the sale of videos through the store on 12 October 2005. Full-length movies became available on 12 September 2006. Purchased audio files use the AAC format with added encryption. I had seen the adverts on TV on how small the nano was but it wasn't until I held one in my hands that I fully understood how small and how impressive these MP3 players are. Weighing only 42grams and a mere 90m by 40m and only 6.9m thick (or thin) these little units are not going to fill your suitcase when you go on holiday. Ideal for putting in your pocket, wallet or purse you can take them anywhere, except the pool of course as they are not waterproofs. The small size does create concerns for me with my children though.

They can easily get lost if not looked after and outside of the home could be easy prey to pickpockets or thieves so beware. They come in two colours white and black and two memory sizes 2gb and 4gb, theses can hold 500 and 1000 songs respectively. For me this is more than enough songs but for those of you with large CD collections, who want to put their whole collection in one place, you may want to go for one the larger iPods. The colour screen looks excellent and shows easy navigation throughout, you can download your tunes into files, albums, types of music etc. My only concern with the screen was, I felt it may scratch easily and some of the cases that you can buy for the nano still leave the screen exposed. My concern is when you put your nano into your pocket or bag and catches something metal. I had heard on the news there had been issues with the early nanos, I still feel this could be an issue.

The main control in the centre of the unit was more touch sensitive than I expected, I use my thumb to scroll the menu, but it wasn't long before it was easy as pie, if fact working really well with the gel case I had bought to protect it. The sound is excellent, I can't tell the difference between CDs and MP3s and I often think those who say they can, can't either. You can download your music from iTunes, a legal way of owning music. They are impressively boxed also, where you open the box like a book and see your nano inside. However you do not get any form of charging your nano except for the computer leads that come with it. This means if you wish to take your nano away from your computer for a period of time you will need to buy a separate mains charger. Which of course is larger than the unit itself? My final conclusion is that this little unit is a fantastic move forward in the music player industry. I was impressed by the larger iPods that my friends had, but it wasn't until the appearance of the nano that I was suitably impressed to put my hand in pocket to make a purchase. And I haven't been let down.

The encryption is based on the FairPlay DRM system. Up to five authorized computers and an unlimited number of iPods can play the files. Burning the files onto an audio CD, then re-compressing can create music files without the DRM, although this results in reduced quality. The DRM can also be removed using third-party software. However, in a deal with Apple, EMI began selling DRM-free, higher-quality songs on the iTunes Stores, in a category called "iTunes Plus." While individual songs were made available at a cost of US$1.29, 30¢ more than the cost of a regular DRM song, entire albums were available for the same price, US$9.99, as DRM encoded albums. On 17 October 2007, Apple lowered the cost of individual iTunes Plus songs to US$0.99 per song, the same as DRM encoded tracks. iPods cannot play music files from competing music stores that use rival-DRM technologies like Microsoft's protected WMA or RealNetworks' Helix DRM. Example stores include Napster and MSN Music.

RealNetworks claims that Apple is creating problems for itself by using FairPlay to lock users into using the iTunes Store. Steve Jobs has stated that Apple makes little profit from song sales, although Apple uses the store to promote iPod sales.[14] However, iPods can also play music files from online stores that do not use DRM, such as eMusic or Amie Street. Universal Music Group decided not to renew their contract with the iTunes Music Store on 3 July 2007. Universal will now supply iTunes in an 'at will' capacity. Apple debuted the iTunes Wi-Fi Music Store on 5 September 2007, in its Media Event entitled "The Beat Goes On..." This service allows users to access the Music Store from either an iPhone or an iPod Touch and download songs directly to the device that can be synced to the user's iTunes Library.
