The iPod is great. Mainly it's for music, but apps are great for it.
Retina Display:
-The amazing 326 pixels per inch Retina Display has one of the sharpest, most crystal-clear displays ever. This means text will no longer be fuzzy when zoomed in, and when not zoomed in, you can still make out the text. In fact, the pixels are so small, you cannot see distinguish them with the naked eye. Wow.
Cameras:
-The iPT4G comes with 2 cameras- front and back. You can easily switch between the two to capture great photos and videos.
-This also includes Facetime. You can video call your friends who have any other iOS devive with a camera.
Storage.
Here is where Apple's Achilles Heel. The range of storage spans from 8gb to 32gb. If you are a person (like me) who doensn't want to spend over £200 on an iPod and loves gaming, then this is a real pain. Apple have got to pull their socks up in the storage region.
Update: storage is a problem?! Not when iCloud comes with a whole 5gb of extra space!!
-Design: Sleek, smooth edges, very subtle lock button and volume buttons. Comes in black or white.
