Yes the iPad is a tablet, Riccardo. "Pad" is a synonym for "tablet."
The introduction video is up and running today, so take a look:
http://www.apple.com/ipad/
After watching the video, I still say this is mostly a large iPod Touch . . . or you might think of it as a large iPhone--
but without the phone. It's easier to use, but it won't fit in your pocket. I'm not what they used to call "an early user," that is someone who loves new tech stuff for itself. The iPad looks like a fun toy. It has some good things and some bad. It has the possibility of using over 1,000 apps, but forget about doing serious photography post processing on it. People will be able to deal with personal snapshots in a number of ways, however.
I own a Kindle, Geoff, which is what your nephew has, I'm guessing. It can hold 10,000 books. It is a primitive device compared to the iPad. But there are no monthly fees with the Kindle--there will be with the iPad, because you can connect to the Internet with the iPad.
I bought the Kindle to try and solve a particular and peculiar problem I had. At the end of the '90s, I got a part-time job as a copy editor at Time Warner's magazine division. This was not a natural skill for me. I'm right-brained, and this is a 100% left-brain job. I found that I could no longer read fiction for pleasure; I could not read fiction without correcting the author's punctuation and grammar. I thought I might be able to read fiction on this tablet gizmo, the Kindle. I have no idea how, but it worked! I began by re-reading the classics: Hemingway, Fitzgerald, Melville, Conrad. Last week I managed to read
The Road by Cormac McCarthy, a most annoying writer from a copy editor's point of view. Another point: Books on Kindle cost $10 or less.
Personally, I will be surprised if Apple has another huge success with the iPad.
