Recently Yahoo! launched a complete re-design of its mobile web search and it is really good with great functionality. Saying it is a web search page is not doing it any justice, I would say it is more of a complete information portal. Yahoo! has been able to seamlessly incorporate OneSearch, OnePlace, and OneConnect togther offering a positive end-user starting point for mobile search . The best experience for Yahoo! mobile search because of the infinite customization options (and hence very long starting page) happen on the iPhone with its ‘easy scrolling’ ability. But the Yahoo! mobile offering for java based smart phones looks very nice too.
Mobile search, is said by some industry observers to be a ‘second chance’ for second tier engines to recapture their glory, but my guess is that will only happen if Google somehow makes a massive mistake. With Googles seemingly infinite monetary and human resources I doubt that will be the case. My feeling is that Google will own a similar percentage of mobile search as it does in traditional search.
