The only version of the iPod which features a mechanical hard drive is the Classic which has been available for several years and hasn’t received an update for a very long time.

Available only in a 16GB version, the iPod Classic can hold 40,000 4-minute songs so you get about 111 days of nonstop music. It is available in either a black or a white color finish and aside from play music, it can also show images and videos on the 2.5-inch color display.
The device is also capable of holding notes, calendars and contacts. It isn’t a very impressive media player but it offers a great storage capacity and is suitable for those who want to travel with a lot of music alongside. If capacity is not important, this isn’t the iPod to get, while some people will not like the user interface, especially those who are visually impaired. We move on to the best iPod available right now, the fourth-generation Touch which you can consider as an iPhone 4 without the phone department. Other than this, it has just about the same features, such as support for HD video recording, FaceTime, an A4 processor, built-in microphone, Retina display, along with front- and rear-facing cameras. Let’s not forget that the iPod Touch 4G does not have the Siri features and is not able to transfer data over 3G or EDGE. While the iPhone 4S has an 8 mpx camera, the one on the back of the Touch 4G has a much lower resolution 0.7 megapixels. In addition, the aforementioned Retina Display is not as good in terms of off-angles in comparison to the display of the 4S. The fourth generation of the iPod Touch is available in three storage configurations: 8GB ($199), 32GB ($299) and 64GB ($399). Even though the Touch is not able to provide the storage of the Classic, the 64GB iPod Touch is capable of holding 40 two-hour movies which will be more than enough for most people. One of the best features of the iPod Touch 4G is the 3.5-inch touchscreen display which manages to be very bright. You get support for Shake-to-Shuffle, Genius playlists, and it also has a built-in speaker plus it can also handle e-mail, web browsing, YouTube and iCloud synchronization. Let’s not forget that it offers support for iTunes Match so you have the possibility to access your vast music library over a Wi-Fi connection so whenever you want you can redownload purchased apps, music, TV shows as well as the ebooks that you have bought from the online stores.
We would like to recommend the iPod Touch 4G to those that want Wi-Fi access to the Internet, iTunes Stores, iBookstore, FaceTime, still & video camera, but can live without the phone capabilities. You should stick with simpler iPods if you want a music player while exercising since the Touch is quite bulky.
