I never handled an iPod touch until a few days a ago. But a friend of mine received as birthday present the media player iPod Touch and so I had the chance to analyze it. What can I say? It's very thin and surprising. Once you start using it, you can not leave it! The iPod touch has a reduced size: height 110mm, width 61.8mm and only 8 mm thick. Weighs only 120 grams. The 3.5 inches widescreen format display has a resolution of 480 x 320 pixels at 163 ppi.

Today, the boundaries between the general purpose PCs, the servers and the embedded systems are more blurred. These computers are sharing same platforms, same peripherals. For example, an x86/Mac PC can be used as a server, an x86/PowerPC CPU can be used in an embedded system like portable navigation device (PND). On the other way, the popular embedded processor StrongARM was a powerful desktop PC processor for the DEC workstation, and the embedded systems often also act servers, like NAS (Network Attached Storage). As same as the hardware suppliers, the OS suppliers port their products into the desktop PCs, servers and embedded systems.
