I understand that someone on the internet has compiled a considerable number of issues for iWork on iPad.

For me, I’ve noticed that Keynote will not loop a playing slideshow. (A good feature if, for example, you had a little file that would talk about services your company provides while you do something else.)

Workaround: export the completed slides to image files. Put them into an iPhoto album and have the iPad play that album as a slideshow. It’s not as fancy, but it will play in a loop until you stop it. And if you make it the one album for locked mode, you can play it without leaving the iPad unlocked.
