I'm one of those who never had any complaints about the N810's keyboard.* I've always found using it a pleasant experience.

Initially, I did not like the N900's keyboard. It wasn't the size of the keys I disliked, but the feel. Additionally, the necessary move of additional characters behind the "blue arrow" to accommodate one less row of keys caused me great frustration while typing. In all, I couldn't achieve the same typing speed I was used to with my N810. However, at this point, I've grown used to the N900's keyboard, and the N810's keyboard has begun to feel squishy.


* Okay, aside from the paint scraping off. That's quite a different sort of issue though.
