iPod Touch functionality question

As with many others, I have faithfully been holding out for this day. However, I do have some questions on how this thing works.

My biggest draw to this thing is that I normally lug a laptop with me when I travel to China and Germany (I do this 3x/year). Now I am thinking with the wifi connectivity, I should have everything I need.
But.....
1. Can I access web based email and have the full functionality of that?
2. Will I be able to view PDF's? (no big need to see other document types)

Sorry if these were covered in the Keynote. i just have not had a chance to watch it yet.

The good news is that my wife, god bless her, has already green lighted me on the purchase. Now its just a matter of sorting out a few details and deciding on pre-order or a quick view at the local Apple Store.

Thanks
