I didn't find anything really upsetting with my
N95. The slider is great, excellent movement when opening/sliding both sides, with great start/end feedback. When open I can barely feel any vibration when typing or anything. If I really pay attention there is a slight vibration, but it's HARD to notice, in my case at least. Great feedback from the keyboard too, excellent screen, small improvements in the OS (finally I can set up a decent workdays recurring alarm), 5 times faster than my N73. And right now I have full GPS signal from 5 satellites from the INSIDE of the house. (which is weird, cause today in Downtown Chicago I din't get a fix around those huge buildings).
Sorry for my stupid jumping around, but I really like this phone A LOT!
To go back, the sliding is nice, with almost none vibration whatever the phone is fully open or closed.
One issue I noticed: I got a leather case that's closing with a magnet. Everytime I place the
N95 inside(locked keyboard) I get it out with the display rotated on the horizontal (like u taking pics or something). I was thinking there is a small sliding involved somehow (cause when u slide the phone to reveal the PLAY/PAUSE buttons it's supposed to turn the screen horizontally). So, it took me 20 minutes to take it, put it back, take it out, didn't notice any real sliding that will cause the phone to do that. I called my wife to look with me at the phone when I do the magic, she didn't see any sliding either. The phone won't flip the screen until it's full open, not if u just slide it partially. So I almost got crazy that the phone is broken or something. When finally my wife comes up with an idea: let's place the phone really close to another magnet. We did, and the same magic happened again: horizontal screen with no slide/button touch. In a few words: my leather case with magnet lock is USELESS !
