The Nokia N95 8GB is a tweaked version of the N95. It has more RAM memory, a redesigned back cover with different build materials. There's also a bigger battery inside and updated multimedia keys. There are plenty of on board software changes too.
Nokia N95 8GB Summary
The screen is improved (both size and quality). The memory is now at 8GB - no microSD slot. Perhaps more importantly the RAM has been doubled.
