nokia 5730 vs nokia 5800?

[hilman]

i want to buy new phone and it comes to this two. both have 2.15mp camera, an xpressmusic phone and use the symbian. 5730 using physical button while 5800 using touch screen. which is better? i never use touch screen phone, just have tried my friend's 5800 and it is quite good but im not sure i can get used to it. the 5800 also have faster processor and bigger screen. but, the 5730 also good. it has a very unique design. the physical button also good. im a teenager, so i think physical button is better for me. for example, typing message without having to see the screen which is almost impossible with a touchscreen phone. im so confused. which should i buy? is it really hard to typing with the touchscreen? please give me a good reason. the longer the answer with more suggestions the better..thanks
