Nope, it's pretty firm. The design isn't as good as the Psion 5, but it's OK. I mainly place it on my lap on something like a book, or preferably, on a desk or tabletop. Then I can type on it at about 60 WPM, which is about 3/4 of my speed on a full-sized keyboard such as my preferred IBM Model M.

I occasionally can't remember where a character is, but I tell myself it's where it would be on a Psion and 20th century muscle memory kicks in and I just hit that combo.

Interesting. I've heard other reports of the hinge wobbling. I wonder if there was a production issue with the material or geometry or something.

Found this random video on youtube. You can see it wobbling at 15 seconds, though mine was more accentuated. https://www.youtube.com/watch?v=opmb6jbeBY4

Interesting. No, I haven't noticed that. Maybe if one particular unit's keyboard works well, you don't have to hit the keys so hard, so it doesn't push down on the hinge mechanism.

Psion's own hinge mech was far better, but PlanComp only licensed the keyboard, not the case. I proposed a fatter "pro" model with a bigger battery that was the same size, shape and form factor as the original, so it'd fit in original cases. I still have several.

I was shouted down by Americans whose internal airlines apparently have or had some stupid limit on the size of battery you can carry on board. In Europe any battery over a certain limit has to be carried in the cabin, so if it fails the crew can extinguish it.
