Colin,
I've followed your directions, and even after entering 50 lines with blanks and 1000's of characters, the tablet is still perfectly responsive with no errors. I have the exact same tablet as you running v4.0.1. Perhaps I need to get the PDF file you are using.
As for copy/paste, if you press and hold, then release on the text annotation, you will see a popup menu with copy/paste options. If you mean copy and paste for sections of text, the Android OS doesn't seem to like me using a floating window very much. I may have to redo the floating text window as a standard control that I hide/show in order to get this to work.
* EDIT
What virtual keyboard are you using with your ASUS? I'm just using the standard virtual keyboard that came with the tablet. Perhaps if you are using a third party virtual keyboard (such as Swype), it may be causing an issue.
