If you get a program like documents to go from the itunes store for $9.99 it includes a desktop version and you can email documents from your iphone to whomever. I'm not sure how good it receives docs as I don't use it for much. You may want to look at quickoffice and several other options as well.
I don't think there are any options for flash in Safari but that would be great. I just watched a video on skyfire and it looks sharp but I don't see that it's available for the iphone.
To me there are some things I wish my iphone could do but of all the devices I've ever used it is the most versatile. So enjoy your 2.5 weeks and then do what's best for you.
Good luck!
