How do you think Google Instant? Here are some opinions about that: TechcrunchTV caught up with Marissa Mayer, Vice Present of Search Products and User Experience, said,"Search becomes easier but it’s still search. The ranking remains stable so people who have optimized their site to achieve a certain outcome that’s still the outcome when users use those queries. So we really think it will be a smaller affect for the SEO community."
it reminds of google wave.. they have this kinda same feature that google incorporate on this update.. and its quite cool.. i really like it..
