IPod nano new generation of products than before the biggest improvement is its built-in acceleration sensor chip, according to the user&#39;s sway and twist and change the playback state, this one has some similar functions and iPod Touch. The new iPod nano&#39;s battery life of official time given up to 24 hours audio, video, up to 4 hours, this is because the new iPod nano&#39;s screen using the latest power saving mode due. And the previous generation iPod nano, the new iPod nano&#39;s user interface has also undergone some changes, thanks to vertical screen design, the menu also lists the special improvement in the bottom of the screen 30% of the area, can display album covers or the details notes, very convenient. The new iPod nano also joined the new Genius feature, this feature can track the style of intelligent analysis system, which combined a DJ-style music player, this feature in iTunes, there are echoes. Nine colors, iPod nano is the largest one in history colors, in addition to the seven rainbow colors include, there are classic silver and black for the user to choose to satisfy consumer demand. The new iPod nano with headphones and decoding programs are not too obvious change, and therefore there was no sound too obvious changes, the new iPod nano is still biased towards treble demonstrated the lack of bass performance, the sound resolution of a well. Original headset, the new iPod nano is also an improvement compared to the previous generation, the sound is more delicate. The new iPod nano&#39;s price and upgrade of the problems have not increased but the new iPod nano&#39;s capacity has increased, the maximum capacity of 16GB and the year has been similar to the iPod Video, which makes the iPod nano has been so small the ability of people with admiration, especially in the current world situation Flash rampant, low price iPod nano also attracted much attention. iPod Touch Apple released the latest generation of iPod time, iPod Touch came out. Judging from the appearance, Touch is simply a streamlined version of iPhone, iPod Touch thickness of only 8mm, basically 60% of iPhone, than is currently the thinnest thickness of the new iPod nano only 1.5mm. iPod Touch and iPhone the same width and length slightly shorter (110mm and 115mm), but higher than the standard iPod Classic of 103.5mm or higher. These are to or from the appearance of size iPod Touch and iPhone able to distinguish. In the overall design, iPod Touch and iPhone also have significant differences. Like other iPod, Touch the surface of smooth, rounded side is connected to the polished metal back cover. tilt both before and after the iPhone has the edge, so that the screen looks like in the frame of the same. iPod Touch&#39;s screen will have to feel the sharp edge of a number. Touch and the iPhone screen size the same, but the edge of the iPhone&#39;s chrome replacement through oxidation of ferrous metals, a width of 2.5mm. Total 5mm black border on both sides of the visual effect from the iPod Touch screen gives a little deeper inside the machine and the screen illusion. In fact, iPod Touch and iPhone&#39;s screen size without any distinction, Apple iPod Touch claims the display fine degree of 163ppi, while the iPhone is 160ppi, but the subtle difference with the naked eye could not distinguish. Resolution of both are 480x320. iPod Touch&#39;s battery can support a nominal 22 hours audio playback, 5 hours video playback. Fast charging, a half-hour can be filled with 80%, fully charged you need to 3 hours. Endurance capacity is slightly worse than the iPhone, which can play audio 24 hours, video 7 hours. However, taking into account the thickness of the iPod Touch case, the gap is understandable. In addition, the open Wi-Fi browsing the web, iPod Touch&#39;s battery life capacity of 4 to 5 hours. And, like iPhone, iPod Touch just below the middle of the front of a Home button. Touch the button body is slightly smaller, the depth also decreased. In addition, iPod Touch and a top power / wake button. But placed at the top right of the different and iPhone, iPod Touch the power button at the top left, for the right to release the location of WiFi antenna. As the iPod Touch is not built-in speaker, so naturally the side of the deletion of the iPhone volume, mute button. In Touch inside, only a simple unit operation can be issued a &quot;bit&quot; sound, all audio players will need headphones. Of course, iPod Touch and no microphone, camera, and the SIM card slot. Touch&#39;s headphone jack near the iPod dock at the bottom of the data interface. iPhone&#39;s headphone jack deep, some joints can not use the headphones are more lenient. iPod Touch is changed this design to support a variety of standard interfaces 3.5mm headphones. Although the iPod Touch can use the Original iPhone headphones, but can not support its remote control function, can control music playback through the host. Those who like outdoor use, hoping to facilitate the manipulation of the user may prefer the iPod nano, iPod Touch is designed for video playback and full touch control students. Since the market since the iPod Touch supports video output, iPhone is a 1.1.1 version of the upgrade through the week, only to support this feature. Previous iPod video output are connected via cradle or headset interface &quot;iPod AV cable.&quot; But this time the upgrades, the new iPod Touch, nano and Classic will be replaced by the base video output interfaces to bear in support of composite or component output. In addition to increasing the Debug Console, iPod Touch Safari browser on the same with the iPhone. ITunes can sync your computer favorites, you can load multiple pages simultaneously, at any time zoom. Of course, iPod Touch only in the context of WiFi hotspots to the Internet, unlike the iPhone version of arbitrary. iPod Touch body functions biggest shortcoming is the absence of Email. (Apple for the iPod Touch recently tailored a number of new applications, which include mail receiving) Although we can use Safari login mail check mail, but users have one less way to transfer files to it. For example, iPhone can view Word, Excel, PDF, etc. files, but not through the data line transmission. The easiest way, you can send yourself an attachment with Email, with the iPhone reception on the line. In the iPod Touch, this road to nowhere, resulting in Touch can not use a variety of documents. If you have a server, you can upload the document and then iPod Touch&#39;s Safari browser to find it, but this is clearly unrealistic for the average user. This greatly limits the scope of iPod Touch, perhaps this is what Apple expects to achieve. Advantages: Wear-resistant metal case and glass Slim, good design Excellent media playback capability Safari browser support for rich Internet applications Pretty easy photo browsing Multiple Web applications can be installed Disadvantages: IPod does not support the new series of slides and other functions of the operating system Polished metal case does not scratch coat problems Does not support remote control or the remote control PDA features a large number of deleted Can not download software iPod Touch 2 Generation Compared to Touch 1 Advantages: Increase speaker Enhanced battery life to 36 hours music video 6 hours CPU frequency increases response speed becomes faster Design a better look at the back arc Increase the Genius functionality Increase the side volume control buttons Disadvantages: Break the immature Stability of the system as before Screen color reproduction variation Work to be less favorable than on behalf of Touch 1 ?
