I am experiencing a kind of writer's mini-nirvana. Yesterday the Big Brown Truck brought me my Apple wireless keyboard. Setting it up was so simple and fast that there was really nothing to it. I was typing with it within two minutes of unwrapping it.
What a gem. The keyboard is fast, accurate, and just sensitive enough, unlike the adequate but somewhat hinky virtual keyboard on the iPad. If anything, it's better that the keyboard on my MacBookó although they are basically identical the action seems better on the wireless.
So far I have used it in several different work environments and with the iPad either close up a la laptop, or further away in "remote input" mode. I never learned to touch type, and usually watch the keyboard when I type. But I'm a fast puncher, working at 60-80 or so WPM. Outside on the deck I can put the iPad on a stand on a table about three feet from my comfy chair, put the keyboard on my lap and flail away. Last night I worked for a while in bed with the iPad lying next to me on a pillow and the keyboard on my lap.
I'm very pleased with this keyboard. In my opinion, based on my experience so far, anyone who uses the iPad as a writer's tool should definitely consider this great tool.
