A touch interface dream that others are still trying to emulate (even the zoom on web pages or other evidence is stunning). A sound quality far superior to that of my 2nd generation NANO provided to replace the original chip unworthy of such a player. A profusion of applets on-APPLE STORE. The WiFi connection is very simple to configure and compatible with all major safety standards. One regret: we can no longer use it as a removable mass media on the PC or MAC (this complicates the recovery of the iTunes library in case of disk crash or computer to change). Delivered free AMAZON in record time: in short, a real pleasure even though the price still hurts.
