I thoroughly enjoy using my Nokia N95 and with the latest firmware it is a solid device that I highly recommend people consider. One of the features that a Star Wars fan like me was thrilled to discover was the N95 integrated accelerometer along with the Lightsabre application. I have had lots of fun swinging my N95 around in fake Jedi/Sith battles. There has been talk of getting iPhone-like auto screen rotation on the N95 and it looks like Samir has made the free utility available on his site. You can download and install rotateMe 2.0 on your Nokia N95, N95 8GB, or Nokia N82 and have your screen auto rotate as you turn the device (N82 requires hot key presses). You can check out a video of the utility in action too.
Another utility that takes advantage of the accelerometer was posted on the Nokia Research Center site and it is called Activity Monitor. The Nokia Activity Monitor is a pedometer that counts the number of steps you take and then displays the data in charts and tables. You should keep the phone on your belt or upper arm for the most accurate count, but you could also put it in your pocket. I need to install this and take it to CES with me this year since I think I walk miles and miles at the event. It does consume a fair amount of battery power so those of us with the N95-1 will want to keep an eye on the battery indicator.
