Could mobile Web browsers unseat IE's dominance?

Richard MacManus speculates on recent developments in the mobile browsing as possibly usurping Microsoft's leading position in the web browser space with IE. I had actually thought MS was doing alright with Pocket IE, which is a tremendous browser that does translation of desktop web content on microdevices really well. Palm's Blazer is also rock solid for accessing the web on a Treo, and Opera's got an app that enabled AJAX on wireless devices.
