Before i start with anything lets see the apple.com about what they have to say about Ipod TouchMulti-touch
iPod touch features the same revolutionary interface as iPhone. Built to take full advantage of the large 3.5-inch display, the multi-touch interface lets you control everything using only your fingers. So you can glide through albums with Cover Flow, flick through photos and enlarge them with a pinch, or zoom in and out on a section of a web page. And iPod touch features a touchscreen QWERTY keyboard perfect for browsing the web in Safari, searching for videos on YouTube, finding music on the iTunes Wi-Fi Music Store, or adding new contacts.
Ambient Light Sensor
The iPod touch display has an ambient light sensor that automatically adjusts brightness to suit the ambient light in your surroundings. The result? A better experience for you and battery-saving efficiency for iPod touch.
Accelerometer
An accelerometer detects when you rotate iPod touch from portrait to landscape, then automatically changes the contents of the display, so you immediately see the entire width of a web page, your music in Cover Flow, or a photo in its proper aspect ratio.
Yeah, we know we're a little late with this one, but we see the iPod touch as a pretty major turning point for Apple's iPod line; when it was announced, we finally thought we'd found an iPod we could really get behind. For years technology enthusiasts pondered the possibility of an Apple-made widescreen, WiFi-enabled portable media device, and they finally did just that -- even throwing in a few things that, prior to the iPhone, we might not have expected, like a full-fledged web browser, internet video player (YouTube), multi-touch interface, etc. But after playing with the touch for a few days, it's become pretty clear that Steve was right when he declared that the iPhone is still the best iPod. Read on to find out why.
Late last year. iPods had fallen into a rut: the features were stale, the form factor of the flagship device basically stopped progressing, and it started to seem like Apple didn't care or understand where portable media players were headed -- or at least didn't seem to realize what such devices were capable of. So it came as no surprise that as soon as the iPhone was announced, people began demanding that same device, sans phone. And why not? Not everyone hates their cellphone, or wants to switch to AT&T, or lives in America (or select countries in Europe) -- and from a media player standpoint, the iPhone made the iPod technologically respectable again. Only a handful of other devices, like the Archos 604 WiFi, come equipped with that specific bundle of features (web browser, touchscreen, and WiFi).

Fortunately for that rather sizable group of potential buyers waiting for the phoneless iPhone, it was clear that Apple had invested an enormous amount of effort (and money) into creating its mobile OS X platform, and that all those development bucks weren't going to live on in only one product -- especially not a device that is ultimately beholden to deals with cellphone carriers. So the iPhone without the phone -- the WiFi-enabled widescreen iPod -- finally started to seem more like an eventuality than some distant hope. When it was announced a couple of weeks ago, the surprise was less that Apple had been working on this device after all, and more the myriad iPhone features unexpectedly absent. We'll get to that shortly.
hankfully, as far as media playback goes, all the best stuff from the iPhone made the cut in the touch. It shares the same audio, video, and photo apps as the iPhone, which is a good thing since we still love the new Apple mobile media interface every bit as much as we did when we first reviewed the iPhone. The iTunes WiFi Music Store works exactly as advertised; search is fast, sampling tracks and downloads are easy, and syncing tracks back to your host computer is effortless. Apple really nailed this. To date, most over the air music downloads on a portable media devices have been tedious, if not completely impractical.
Also unchanged are our primary complaints about said media playback, the same complaints we've had about the iPod for years: we don't like managing our media through iTunes, and we don't like being limited only to those few codecs Apple supports (AAC, MP3, H.264, and MPEG-4). In fact, if Apple gave us greater codec support (or even just the option to add additional codecs ourselves) and mass storage support for drag and drop while adding media, we'd probably be able to overlook the other, smaller things that ail us about iPods.
Software




But it isn't what's on the touch that caused us to sit up and take notice so much as what's not on it. The iPhone's suite of apps set certain expectations for what the touch should include. Granted, we understand why the iPhone's mobile email app was omitted from the touch. While we still would have liked to have the option to email over WiFi, its intended purpose is as a portable media player, not a mobile communicator, so we can follow that line of thought. But why leave out its notes, weather, stocks, and Google maps apps? We know the portable doesn't include the same constant connectivity as the iPhone has with EDGE, but it's not like downloading music over the iTunes WiFi Music Store is a practical application in ways that checking for weather, or jotting down a quick note are not. The touch is still a connected portable device, after all, and what we see is Apple mimicking the limited feature set of the old, stale iPod line instead of fully realizing the touch's potential.


For a company that continually emphasizes its software as being the core of what drives great consumer electronics, we just can't understand why Apple chose curb the touch's capabilities right at the outset.
Hardware

Hardware volume controls were highest on the list of things we miss. We could just as easily live without a mute switch on a media player, but losing the hard volume buttons is rather disappointing. Granted, Apple has made it easier to get to the media controls and volume when the device is in sleep mode; just press the home button three times (once to wake, two more times to bring up media controls without unlocking it). But what's wrong with a real volume switch, too? With no hardware controls, doing something as frequent and essential as changing the volume necessitates removing the device from your pocket. Furthermore, without hard volume buttons, you can't adjust the volume at all while playing music in landscape (i.e. Cover Flow mode). This is pretty basic stuff that drives us up the wall.


Then there's the matter of the display. Ours happened to be one of the "small number" of touch units with the faulty screens. It's difficult to capture in a photograph or even explain in text (so far the best shots we've seen came from Apple-Touch), but the result is dark shades -- especially black tones -- look almost inverted. At very least it's distracting, and at worst it makes some darker video almost unwatchable. We hope Apple gets these units fixed on the double, because for us this janky screen teeters on the edge of a return-your-unit-forever dealbreaker.

Wrap-up
It's hard to argue that there isn't beauty in simplicity, especially when it comes to consumer electronics. But there's such thing as too simple -- and sometimes too simple can turn into crippled. Most of our complaints about the touch have to do with what it lacks -- not in general, but when compared its big brother, the iPhone. Had the iPod touch come out first, the lack of a hardware volume switch, integrated speaker, and all those apps might have been perfectly passable, but now the expectations have been set, and we can't see how taking things away from users can possibly add value. Everyone in this industry is trying to give their customers more, but with the iPod touch Apple gave its customers less in what should have been the best iPhone alternative on the market. This time around, in Apple's obsession to edit, they managed to leave some of the best stuff on the cutting room floor.
