I can only tell you about my own experience.
From almost the very day I got the iPad, my notebook became a "work" machine and my iPad because my "pleasure" machine. I use the iPad nearly exclusively for e-mail, for casual surfing, for watching videos, for looking at photos, playing games and other "leisure" activities. I almost never use my notebook for this anymore.
The iPad, being lighter and lending itself much more to being both portable and couch-or-recliner use, brought a whole new experience to these tasks since I didn't have to either a) find a desk or b) assume the notebook position to use it. It's hard to describe in text but the experience is WHOLLY different to the traditional use of "a computer."
In particular, watching videos with headphones on an iPad is just SO much more pleasurable than watching them on computer, and if you throw an Apple TV into the mix you can just "toss" videos from the iPad to the Apple TV and its connected HDTV effortlessly. It's one of those moments when you realise you really are living in the 21st century (ie doing something nearly unimaginable in the 20th century, never mind cheap and easy!).
I personally also now prefer to read books on the iPad (I was previously pro-paper). I can spend HOURS gazing at photo websites or my own collection on the iPad. It's just great and has really changed my relationship with my notebook (my main computer) completely, not to mention giving me more reasons to read magazines, books and watch videos or play casual games.
I should also add that I no longer feel the need to bring my notebook with me on personal trips, which saves several pounds of gear compared to the iPad. Somehow the device gives you a MUCH greater sense of freedom (particularly with its long battery and option for 3G) than a notebook does.
I also enjoy getting questions about it whenever I'm out in public and showing it off to people who are always quite amazed by the versatility. Throw in a Bluetooth keyboard and it makes an IDEAL creative writing tool thanks to its size and option for vertical ("paper like") orientation.
Hopefully that will answer your question.
