Which keywords should I use?

I have a new smartphone ~ Samsung Galaxy S II. It is a great phone but bad compare to HTC HD2 in SEO term. Why? The official Samsung Galaxy S II keywords does not always return the search result that I want. Samsung Galaxy S (SGS1) results were returned some time. Therefore, I used Google Trends to check its search volume.
