The View firmware is different, in mi4 format, using the NVIDIA chipset. The Fuze+ solves many problems experienced with the earlier device, having a nice display for video, and it’s more open to various video sources.
The Fuze+ uses the Freescale processor, a new device for the Sansa, with firmware in the sb format.
I like the seamless way the AMS processor Sansas handle audiobooks, this includes the two Clips, the e200v2, and the original Fuze.
For the Fuze+, development and “tweaking” of the interface is ongoing, just like the previous models when they debuted.
If you have a look at the motherboard of the View, its population of chips is stunning, it has a lot of hardware in there.
