Why not design your own website? First of all, it will most likely look like you designed it yourself. Unless you have a few years in website design and understanding of how they work, it will probably fail. Every time I hear those commercials, I cringe.
I can't say enough good things about responsive website design. Combined with a powerful CMS like Drupal, it becomes an incredibly flexible method of delivering content for any device. It's an efficient way of delivering your content so it looks good and fits in any size display.
Responsive design for websites isn't the latest innovation in website design and development but one of the most effective. It eliminates the need for alternate theming to accommodate different size devices such as smart phones and tablets.
