I’ve not used a tablet myself, but it seems more an entertainment curiosity to me. Maybe others can give some insights i don’t have.
I think you have it right. A lot of users just want to send email and surf the web. Tablets are good for that, very portable and very easy to use. In the past some users have had $1500 desktop machines and used them for surfing the web. That behavior is going away.
Power users won't be happy with tablets, but power users know enough to stay away from tablets for any serious work.

If all you do is watch videos, view web pages, read ebooks (for those who actually do read books) and play "Angry Birds", a tablet is perfect. It's easy to carry, the battery lasts a long time
They are terrible for producing content, which is why PCs aren't going away any time soon.
