PDF viewer is now officially the dogs bollocks. I've opened a 2meg PDF with colour images etc. No memory problems, paging is definitely fast enough - 4 or 5 seconds to page text, about 10-15 with colour images. And that's with 2 web browser windows open.

Update: 8.8 meg, 120 page, document opened in less than 10 seconds. Skipped to last page in less than 5 seconds. I'm seriously impressed with that because I can now put all of my Open University books one one card and keep them with me.

OK, so it's not all colour but even so, a huge improvement.
