I used to own this back in 2008 / 2009 when Nokia used to be king of the mobile world.
At the time, I liked its design - it has a dual slide action so if you push it up, it will reveal the keypad like most standard slide phones, but if you push it downwards, it will show a row of tactile keys that you can use whilst using the music player. I found these handy as I could feel the buttons whilst I had the phone in my pocket.
The build-in 8 GB of memory meant I could save all my music onto it and listen to it on the move.

I own a Nokia E66 and software wise both can run the same kind of applications. I remember using Nokia maps on my N95 8 GB but I found using an external Bluetooth GPS receiver was the best way to get a signal. The in-built receiver sometimes struggled to lock onto a signal.
You can use the BBC Iplayer site using this which I liked. It won't let me do that on my E66.
It was very slow - it used to take forever to load the text messaging application and read SMS or do anything else for that matter.
Call quality was good and the battery could last for a few days but I bought a backup one off EBay for a few quid.

One of the minor design niggles I had with it was that the 3.5mm headphone jack was on the side of the phone instead of on top or bottom which made it quite awkward to listen to music when I had it in my pocket.
Also, the screen used to shake quite a bit when I used to slide it open to show the keypad. The screen wasn't attached firmly to the runners / rails. It made the phone appear like a toy. It is also made mostly of plastic which makes it appear more toy-like as well. I now own an Nokia E66 which when you slide open, has no movement in the screen at all. It just makes the phone feel more solid.


* Summary *
A great multimedia Smartphone at the time with one of the best cameras (5mp) but it is not worth buying this brand new.
I could only suggest it to people who maybe prefer using phones with buttons as this has very easy to feel keys.
