The iPod Touch feels just right; its gently-curved back lays nicely in the fingers, like the iPhone 3G but even slimmer. Its shiny metal back is prone to scratching, like all the classic iPods. Apple includes a microfiber polishing cloth, which we use as much for the metal back as for cleaning the glass face where you manipulate the user interface with your fingers.
The original iPod Touch had some excess noise in its amplifiers, noticeable during very quiet passages, but Apple seems to have fixed this. The iTunes Genius feature, introduced with iTunes 8, works on iPod Touch, and it’s great.
Though the iPod Touch can’t play HD video like a desktop Mac, its display is only a quarter the size of HD, so this isn’t really a deficiency.Its the least expensive entry to revolutionary mobile Apple platform, huge apps ecosystem; works as PDA, media player, game and application platform, very good performance, speaker and volume control.
