Someone asked, so here you go. I just made a short video showing the major changes in webOS 1.2:
YouTube - Palm Pre Running webOS 1.2
Still processing, not sure how long that'll take, but viewable now, HD will take longer.
I know I didn't get everything, but I didn't want to display any of my private information so I skipped some things. For the full list check Elysian's thread:

It shows most things that I could think of off the top of my head while I was making the video though, I'm sure there's one or two small things I forgot too.
