New mobile ecosystem
More bandwidth: EDGE, HSDPA, WiFi phones, WiMax
More processing power & memory: enabling big improvements in user interfaces (iPhone)
Increasing off-portal mobile internet traffic(10-20% in US, 40-60% in W. Eur)
More mobile-friendly Web content (5.7m dotMobi and WAP pages, up from 2m over 12 months)

Slide 4
Implications
Mobile browsing will take off, especially off-portal
Clusters of devices emerging:laptops (0.8-1.2MP), HiPhones, (160-300KP), MidPhones (80KP) , LoPhones (<40KP)
As content broadens, search becomes the de-facto interface to all mobile content
But mobile search must work well across all device clusters

Slide 5
Reality check: mobile search today
Sources: Nielsen Netratings May 2007, M:Metrics Feb 2007, Pew Internet May 2005
Desktop internet: 490bn searches pa
Mobile internet: 3.1bn searches pa
Small screen issues- need for brevity- 10 taps or under
Mobile network issues- network latency- inspection of results- data charges
Relevancy issues- desktop Webcontent often not mobile-friendly

Summary
Mobile content growing fast, as is mobile browsing
Realization that search is the de-facto interface to the online world, as content increases
Mobile search needs to work better - usability gap
Social-assisted mobile search can drastically improve usability – 30 clicks down to 8
Now we need to extend to all the other categories, from 25 items to 1 billion items
