I really like my keyboard dock, too. I plan to do a fair amount of writing on my iPad and I find typing on it very comfortable. However, the keyboard dock must be placed on a flat stable surfaced or the vertical iPad rocks out of it, but that's okay with me. No typing on the couch with it; if that's what you want, I think there's a Bluetooth keyboard that would work better for you.
Agree with you on all counts Ghuda. I am a new iPad user and still going through the learning process. I just wondered if there are a few more Keyboard tricks we are unaware of, like some way of closing down, like the Smart Cover does when the Pad is wearing it. KB.
