The keyboard fine for extended (>1 hour) Internet usage like the web, e-mail, IRC and Jabber. It's also fine to write notes that are a couple of paragraphs long. There is no way I would write anything longer than a trivial one liner using the N810's keyboard. I write code and build binaries using a desktop PC.
Some annoyances with the keyboard are:
The top row of keys are too close to screen edge making things clumsy to target them.
It's clumsy to hit the correct key because there isn't any gap between each key.
I think there isn't enough tactile feedback when depressing the keys making the typing experience less satisfying than its potential.
Despite these failings, the keyboard is far superior to touch screens with tactile feedback.
