I want to develop some iPad-specific websites. I thought, first and foremost, I should probably know what user agent the iPad sends to identify itself.
Once I was at the Apple store in Buffalo, I got in line, waited about twenty minutes, and was inside the store with one in my hands. I visited one of my sites, first thing, and then looked at my server logs when I got home.

Here is my iPad set on Flickr, if you want to see more..
The user agent string reported was:
The user agent reported on Apple's site only differs in Mobile Safari version number, to the one that my website logs reported from the final launched iPad.
I became interested in this as a web platform when it was first announced. Since then Google has even made a version of the Gmail interface for iPad users.
You can see the iPad version of Gmail in person, without an iPad if you spoof your user agent.
I did this using FluidApp:
Refresh the page in FluidApp, and you should see the email items in your inbox listed in a pane on the left, with a larger right pane, viewing the message you're currently on.
