The first iPod ever made, was
iPod classic. Although it didn't have this label, iPod classic is supposed to be the continuous evolution of the first iPod. This is adequate in a certain matter of looking to the picture. You see, Apple concluded that the classic iPod line is the successor of the first iPod ever made. Apple only used this pretext in order to keep the iPod legend alive. However, the first iPod will always remain a milestone element in Apple's history. Since October 23, 2001 iPod classic is the best sold iPod for the time being.
Until today, iPod classic has reached the 6
th generation improving its specs list in a dramatic way. The classic logo was added to the iPod on September 5, 2007 on the same day iPod nano 3
rd generation was released along with the iPod touch.
Therefore, the iPod classic we now know of is part of the new iPod line rebranded over two years ago. The controls found on the 6
th generation of iPod classic are the same from the 4
th and 5
th generation, included in the click wheel (Menu up, play and pause down, right skip forward and fast forward, left skip backwards and fast reverse, while the center is the ok button). The first generation sported the scroll wheel, while the 2
nd generation and 3
rd generation included a touch wheel. The
iPod classic's memory over the last eight years increased from 5 GB to 160 GB. Nowadays you can find the 6
th generation of iPod classic sporting an 160 GB internal memory which should be enough for 40000 songs in 128 Kb per second AAC format, or 200 hours of video (H.264 with an average 1.5 MB per second video 640 x 480 resolution, with 128 Kb per second audio), or maybe 25000 pictures.

The design offered by this second revision of this
6th iPod classic model is the same as the previous model. The front cover sports the click wheel under the display and a matte plastic cover (either white or black), whiles the back sport an anodized aluminum and polished steel lines around the iPod classic sides. With a height of 103.5 mm (4.1 inches), wide of 61.8 mm (2.4 inches), deep of 10.5 mm (0.41 inches), iPod classic weight about 140 grams or 4.9 ounces. It is not the smallest design out there, but it can sure hold your entire media library.

On top of the classic you get the hold switch.
iPod classic contains a frequency response of 20 Hz to 20000 Hz. It supports a few audio formats such as AAC (up to 320 Kb per second), MP3 VBR, MP3 (up to 320 Kb per second), and other formats such as WAV and AIFF. The video is quite narrow in compatible file formats. You get H.264 video support, and MPEG4 video support. You can easily configure this two video encoding however you like, from resolution to audio profile. Beside the audio and video compatibility, iPod classic also brings some other features such as the Genius Mix, or iPod games, and even the TV out feature (connect iPod classic to a TV by using an optional Apple cable, composite AV cable).

Apple included in the iPod classic, since 2008 a 2.5 inches color LCD with LED backlight sporting a resolution of 320 x 240 pixels. Other ports and jacks on the iPod classic are the dock connecter, and the 3.5 mm audio jack. The current iPod classic model features the 2.0.1 operating system (being the seventh operating system offered by Apple for the iPod classic). The USB connectivity is present on the classic iPod models since the 4
th generation, while the first and second generation only had Fire Wire (the 3th and 4
th generation sported both Fire Wire and USB connection).
Because Apple wanted to improve the iPod classic battery life, it replaced the Lithium Polymer with Lithium Ion battery. The current iPod classic has a music playback time of 36 hours or video playback time of 6 hours. It takes about 2 hours to charge the battery up to 80% and it will take about 4 hours for a full charge. If you are interested about system requirements then you should know you need iTunes 9 or later to connect your iPod classic with your computer or MacBook. Apple ships iPod classic with earphones, 2.0 USB cable, dock adapter, and a quick start guide in the retail box.
Therefore,
iPod classic is an excellent choice if you are looking for a media player that not only looks great but delivers everything it's supposed to. Also, the huge internal memory of 160 GB of the iPod touch is more than a bargain for the $249 price tag.
