If it's Ok to hijack this thread for a moment, I've always had a nagging issue with i-adjectives. The above sentence sounds perfect to me, but Tae Kim was always adamant about not attaching copulas to i-adjectives as you did. So, is your sentence correct? Or is it not purely grammatically correct, but colloquially accepted by native speakers?

You need to buy a book and learn from there. seriously. Its obvious your struggling along and at this rate you wont get anywhere. Sorry but im just saying it how it is.

No one ever learned a language by posting on a forum..

thanks but i just want to see if the way i am using grammar is correct.

Something I'm yet to understand...could the be を used instead of the が?

What's the difference?

Buying a book is the difference between knowing and not knowing.

が　Is a particle that works like は　but marks something less important and the main sentence.

を is an object marker.

たかはしーさんはすしがすきです
Mr Takahashi likes sushi.

たかはしーさんはすしをたべました
Mr Takahashi ate sushi

Hope this helps.

I only use が in "が好きです" so far. What you wrote I already know, but thanks, I just thought there were more differences.

As for the book...I wish I could, is not about the money, I just can't find books here in Portugal, I already ave one but it's for kanji and it's not the best, I wish I could buy from sites like ebay or so, but I can't nor I trust. And my parents woulnd't let me (buy from there).

Have you not got a trustworthy friend or family member you could ask? show them what you want, give them the money in hand and go collect it from theirs when its come? :)

Highly doubt it :|
However, I always go look for books in librarys and in portuguese online shops, find a few, but not the best...I still do it, as a matter of fact, I'm glad you remembered me :)

I once was to buy "japanese with ease" all volumes (3) and went to two shops who reserved it and after a while they told it was sold out.

What worries me the most is not the grammar though...it's the kanji. I already have some knowledge of the grammar, verbs and stuff...I always got confused with the ga and wo.

As per the original thread I guess what he tried to do was using the adjective in both his uses:attributive and prdicative. He made a little bit of confusion with the demostratives, but I assume what he wanted to write was:
この時計は高いです　=> kono tokei ha takai desu.
and
これは高い時計です => kore ha takai tokei desu.

As per the question of TaeKim I might not be the best one to answer this, maybe a native would be more appropriate. However, in TaeKim site he states in the beginning that his course is not aimed at polite/formal speech. What he wants to offer is a more "friendly spoken" Japanese. True the copula だ can never be used to support an i adjective, but the です yes. I think what TaeKim wants to get at is that in that case the です part more than copula has the role of a politeness particle, thus since he offers as more friendly inclined speech he prefers to omit the です at the end.
