In ealy September, MSN's new search rollout introduced tabs on their personalized homepage. I predicted Google would follow this useful UI approach within two months. I was wrong. It wasn't two months, it was two weeks: Google personalized home offered tabs on 14 September. In that post, I considered if Windows Live will increase MSN's search share, and concluded it would not, because long term, a great personalized ajax desktop offers little competitive advantage, as the major search engines adopt good ideas from one another too quickly. I stand by that conclusion.
