I just brought this up on the iPad. I realized that I'm in bed with my knees up. It's unconscious! Whatever you find yourself doing with a book or a magazine, you unconsciously do the same with an iPad. To me, this is a sign they got the form factor right.

Update: lie in bed and browse one handed, but roll to sit on the edge with crossed leg to post. Again unconscious and noticed after the fact.

First annoyance: Have to go back to my laptop to copy-paste and quote another HN post for a reply. Can't double-tap to copy!

Solved by one second of tinkering: doubletap-drag to use copy-paste!
