No I didn't buy one (yet). But I got to play with one extensively yesterday with the wireless turned on.
The short of it it is amazing. Particularly for multimedia content, pictures, pdfs, and movies. As a computer it is so-so Apple (and Jobs) are too obsessed with created a walled garden for the iPad be outstanding as a computer. But with the multimedia stuff the future is now.
I was able to open up full color PDFs and effortlessly read them zoom in an out at will. Even with the full page filling the screen it was readable for the most part. Images were great, I was able to open up some of my maps and be able zoom in and scroll around in full glorious color. The Safari web browser was pretty good. I liked how it handled multiple web pages. You can hit a icon on the top and a screen opens with multiple pages that you viewed. You can create a new slot and fill it with a page or just touch one of the other pages and immediately go to it. Very nice indeed.
With the right applications the iPad can be a killer device for gaming. The key is to use the touch interface to have multiple stuff loaded and be able to switch effortlessly between them.
Like the Kindle in the beginning the price is too high to be of general use but it will drop. When it get under $200 I predict it will start picking up steam.
I also got a look at the Kindle 2 last week and it is improved over the first version I have. The increased number of grays it can display really helps. Plus it can show PDFs natively and has the ability to switch orientation when you rotate the display. Plus certainly the price is way better now with it being at $189. Barnes & Noble Nook is even lower at $149.
All of this happening a little faster than I thought instead of 10 years I will go with the prediction that within 5 years we will see devices that will make a major change in how we buy and consume gaming products. For example for D&D 4e fans imagine a setup that now only has your three books loaded but also had the entirely of DDI loaded as well. And it displays like a regular character sheet.
