Look and Feel:
The Nokia X6 looks sleek and modern, and is also relatively light. It maybe slightly on the thick side when holding with one hand, but not so much that its a problem.
The three buttons are on the front are easy to use, and the sliding hold button on the side of the phone is fantastic for quickly locking or unlocking the phone

Touch screen:
The Nokia X6 has a capacitative touch screen, meaning its very responsive to your touch, and I have never found myself having to push hard to get a response.
For writing texts, the phone automatically changes to a full QWERTY keyboard when the phone is placed in landscape position. This is much faster to write with, but users may find themselves mishitting the odd letter in this mode, which can get annoying at time. In such case the predictive text used in the portrait 9 button mode can be easier to use.

Music:
As far as music phones go, this one would hit somewhere in the middle. The on board 16GB or 32GB leaves plenty of room for music, and the screen is of decent size and quality to watch music videos comfortably. The sound quality however won't see you leaving your ipod or mp3 player in the draw. It's not poor by any standard, but certainly quite average for a music phone. Luckily there is a standard 3.5mm headphone jack, so using your favourite headphones wont be a problem.
The 32GB version also comes with free music downloads for a year from Nokia, so you can save a bundle on that.

Software and Hardware:
The phones software is simple and easy to navigate, with the standard Nokia style menu and some small customisable options on the home screen, such as a favourite contacts bar or email display. These options are useful but very limited. Don't expect to be able to tailor this phone to your needs.
The Nokia Ovi suite provided on CD is however excellent for syncing and transferring all information from your phone to your computer, including contacts, messages, videos and of course music. Takes no time at all to sync and you can be sure your information is safe on your computer.
The Nokia App store is vast improving and some great free apps can be found there. Not rival to itunes, but not too far short.
The phone comes with GPS, excellent when your lost. The free Ovi Sat Nav from Nokia is decent when in the car, but on foot i much prefer google maps.
I find myself charging the phone just about everyday so i can be sure it wont run out when i'm playing music or looking at google maps, but when used lightly it can last about 2 days.

Camera:
The 5MP camera takes pretty decent photos when the flash isn't required, with a quick shutter speed and not too much lag. It has various scene settings and customisable features to get the most out of it, with pictures being sharp and full of bright colours. The LED flash isn't great for taking pictures in the dark however, but it's still a decent substitute when you've left your camera at home.
Video capture is again decent, but only useful if you have nothing else around.
