@anjin ... it seems the keyboard is very important for you. While @tzsm98 says you may like the keyboard a lot, my experience is not the same. I wished the keys on the n900 were a lil bigger and sensitive to touch, I have to push and press the keys more then I want to. My friends say the same about the n900's keyboard, long chats can be a lil unpleasant. So I'm not sure you will like it or not and I will really advise you to try your best to spend sometime writing on n900 before you buy it.

Btw about the home screen customization, I think n900 has the best home screen that no other handset, even these days, can match.
