There are a couple different videos floating around on YouTube and these forums with little previews of the N95. The search button is your friend on that one. The UI is as fast as the N93 since it uses the same processor. They have clips of it running SRE (like the N93 does), the response time of opening the camera, and how fast it switches to landscape when you slide the phone into its "music mode" or whatever. Of course, this is all on pre-production firmware, but that's still pretty good.
