The several main factor when looking out choices of smartphone:
1)Design~ must be suit to most of condition, not too heavy and handy.
2)Camera
3)Music
4)Interface/platform
I've borrow my friend's phone (iphone 3gs) and i use it for few hours to see whether it's true that Nokia N900 (which currently i'm using) is better than iPhone 3gs in most of aspect.
What i can see,
what i can feel,
when i'm browsing the web, it seems to be that N900 give be the best in term of perfomance and loading of all graphic, picture and animation in each of page. What's actually iphone doesn't have Full Flash 9.4 as like as N900. With full flash, i can also play games from facebook similarly like playing on laptop/pc.
Although N900 is still under development, it beats iphone 3gs interface as N900 widgets and icons logically give me a better navigation as it has 800*480 display screen allow me to have almost of all application shortcuts on the wall.
The QWERTY keyboard is another aspect that adds value for your money as you might get dificult of posting huge entries on website, or even writing long notes. N900 gives you choice of using the onscreen kyboard layout if your too lazy to slide out the Qwerty keyboard.
