Hmm, I remember reading somewhere that you don't use なの after i-adjectives and that なの=だ+の.

Like kouhiichan said, なの=だ+の. Where you would need だ, you need な before の.

なんです (or なのです) gives a sentence a tone of explanation. It's used in a question to indicate that you want an explanation and used in an answer to show that it's an explanation.

のです is used in the same way as んです, isn't it?

Yes.

Thank ya, sir (or madam).

Well, you wouldn't say おいしいだ, but you can say おいしいなのよ or おいしいなのです. However if you want to form it in a (possibly girly) question, drop the な: おいしいの？ (Of course you can also say おいしいだろう and おいしいな, but this な＝ね、not だ)

[p]As well as なんだから/なんですから and なんだろう/なんでしょう?[/p]

なんだから is to emphasize an explanation: もう５年生なんだから、もっとしっかりしなさい。
なんだろう is used for asking what something is: あれは何だろう？

Oh, I think I get it now. Thanks!!

And um, one more question. 何だ and なんだ(なのだ) aren't the same thing, right?

I started a thread here about something similar before: http://forum.jisho.org/discussion/480/naadj-at-the-end-of-a-sentence/#Item_0

You don't use なの at the end of i-adjective, but you can use の or な/なあ.

Sure. Yes. (By the way, I'm not sure if なのだ and なんだ are completely the same. I don't know if you can use なのだ for a question, but なんだ is very common--あれはなんだ!?!, or as I prefer あれはなんなんだ!?!)

No. Like you correctly showed, 何だ uses the kanji for "what". なのだ doesn't share that meaning at all, though of course, 何だ and なんだ are pronounced the same.

Sorry about the confusion in my comments. Tobberoth's right. I wasn't thinking clearly. なんだ could either be なのだ or 何だ. I don't often think about these things anymore, which is why I like this forum! Thanks, Tobbes.
