Apple apps should all have been ready for the iPad.
I will work off of ob81's list to answer this question. First, the iPad exceeds my expectations in ease of use of and it's potential to be both a good content consumtion device as well as a productivity tool for content creation.
And, it's fun.
The screen is crisp and clear, multitouch is very responsive and the battery life is outstanding.
About 3G:
If you are waiting for the 3G model, consider yourself smart for getting 3G. I didn't see the importance of having 3G because I have not had the need for 3G on my MBP. Well, the iPad is not a laptop so I was wrong. The apps that run on the iPad are the same ones that run on the iPhone so it makes since that many apps run better with constant connectivity to the Internet, which wifi cannot provide. I can't download newspapers, books, or any other content when I want without 3G, which sucks. But, the 3G ipads cost too much and I don't like paying for a third Internet connection (I have one on my iPhone and my cable service - isn't that enough).
great.
(the email program works fine, and Pages is one of my most important apps - I think an iPad version should be standard)

(Many of the apps designed for the iPad have a better look and feel than the iPhone versions)

(I bought the keyboard dock, but that purchase now seems unnecessary)

(I Agree. In fact web surfing in general is fast, but not great. Typing urls feels clumsy and creating bookmarks is easier and more useful on other web browsers that can't be used on the iPad)
