The first-gen nano, in retrospect, was no great shakes. It had limited functions and the small screen went against it. The second was cool too, while the third-gen nano had a new chic look, with video capabilities and a bigger, sharper screen. It was worth its price, but I still couldn't understand why the capacity had to remain the same.
Now, with the new nano, I have to say a lot of my prayers have been answered. It has a sleeker look, a lot of new features, and more colors (nine, but only eight available in India) to choose from. The space has been upped to 8GB and 16GB. Let's see if its worth the deal
Design and UI performance
While the second-gen nano was a sweeping change from the first, the new series from the Chromatic line bears an uncanny semblance to it. It's gone back to a taller form factor, and the screen has become sharper. A good two inches (diagonal) is exactly what you need, and the sharpness and contrast has only gotten better.
Thin is in. You don't believe it? The new nano has been beautifully shrunk and there's a nice affected curve that I like. Hold the nano perpendicular to your line of vision, and you will notice that not only are the edges curved; the bend runs through the course of the body too, including the screen.
How did they manage to do that to the screen, you ask? Well, they didn't! Look closely and you will see that the screen is actually flat, and insulated by glass covering. The body is all-aluminum, with glass for the screen. The depth is just 6.2mm, while the height and width are 90.7mm x 38.7mm. All in all, a neat design.
The piece that we got for review was blue, and although I wouldn't go out of my way to pick this particular color, I must admit it looks pretty good. The white of the wheel and the Apple logo are done pretty well.
The click wheel is a wonder to work with, and it's very responsive too. The nano doesn't take any time at all to start up. Keep it on hold after switching it off; a tiny jab will get it up and running. The overall performance of the player makes it a wonder to use... something that isn't easily forgotten when you have 8GB or 16GB of content to pull.
ipod 3g looks better tan 4g,its smaller and more stylish...its havin the same screen size and 4g cost is more than 3g when i bought it
