The iPad, to me at least, feels like very possibly the best internet surfing device out there.
It is small and light and portable (smaller, lighter and more portable than a netbook), it gets insane battery life. And if I want to look something up online, it is apparently almost as fast as thought. It is get iPad, press button, hit safari, start typing. Just that fast apparently. I don't know about you, but my desktop doesn't open up any web browser (in any OS) that fast, and I know that a netbook can't. Want to send an email? Instantly the email app opens, want to watch youtube? There's an app for that. Want to surf porn? A lot of the major sites have revamped their selection so it is iPhone compatible.
To me though, the biggest thing holding me back is the annoying extra step to get my AVI TV rips onto the device. I use my PowerBook at work to watch movies and TV shows (helps pass the time), something that I won't be able to do as easily on the iPad.
