N9 has swype, and I use it all the time. While I can't give any comparisons to N900, I can give comparison to N950. Even with N950's hardware keyboard, I prefer typing with swype with N950. It is only rarely when in command-line I prefer to use hardware keyboard.

But basically I agree with other people's suggestions. If games are a big thing to you, get Android phone. N9 is great, but the game selection is much better on Android.
