Pros:
Vibrant screen. Every single pixel is better than a budget Nokia phone.
Wallpaper slideshow. Press and holdc key to change wallpaper.
Hot swappable card slot. No need to remove the battery to insert memory card!
Very good camera. Although its just 1.3 MP, the quality is good.
Good keypad. Easy to type. Large keys. Back-lighting rocks!
The keys are still awesome. Its still sheen, even after an year of use.
The phones fast. Everything is very, very fast. Nokia phones are always slow.
Menus can be navigated with the keypad. For example, to change the screen brightness, pressing [Menu] followed by 3, 6, 2, brings you the menu where you can change the brightness.
The look of the phone(front side) is amazing! The back side is not very appealing.
The stop watch and the timer functionalities are also good.
Using Bluetooth, the contents of the connected phone can be browsed. AFAIK, Nokia cant do it.
Cons:
Not a single app can be installed.
Music cannot be played in the background. We can only send and receive SMSes when we are listening to music.
Only 10 events can be stored in the calendar. Funny, isnt it?
The memo pad also can store only 10 memos.:(
Certain keys dont have back-lighting.
