At the end of 2007, I bought a piece of iPod nano mp3 player, it's so good that i never let it take out my hands.I listened music every day as soon as I could put earphone into my ears.
I must to say it has quite a wonderful sound, fun colors and good video display, considering the screen size.
Though I have used it for more than two years., it is still as good as that I bought it from store.
Why could iPod do like that?I could explain it as follows:
For most of the iPod video's functionality, we're dealing with seven primary components:
· Hard drive - 30-GB Toshiba 1.8-inch hard drive
· Battery - rechargeable lithium-ion (700 mAh, 3.7V)
· Click Wheel - navigation via touch-sensitive wheel and mechanical buttons
· Display - 2.5-inch TFT LCD
· Microprocessor - PortalPlayer PP5021C with dual ARM7TDMI cores
· Video chip - Broadcom BCM2722
· Audio chip - Wolfson Microelectronics WM8758 codec
iPod's battery is completely built-in -- you can't just pop in a couple of new AA batteries when it stops charging. This built-in battery has been a headache both for iPod owners and for Apple.
Originally, the iPod battery was not only non-user-replaceable, but it was also very expensive to replace via Apple. When your battery died (sometimes within a year of buying the iPod), you had to send your iPod to Apple for a replacement, and the new battery cost $100. A lot of bad press and a class-action lawsuit later, Apple's iPod battery-replacement program costs $59. The class-action suit was settled, and iPod owners listed in the suit were compensated with $50 vouchers and partial refunds for their $100 battery replacement.
Apple defends the use of a non-user-replaceable battery by explaining that the built-in battery allows for the ultra-slim form factor for which the iPod is known.
Maybe from all what I have said you still could not know exactly why?
