We mentioned Deepfish way back before WMExperts was really really live, but it looks like it's making the rounds again. Deepfish is a new browser for Windows Mobile that has some really nice zooming features (ala iPhone). Sadly, it appears that they're not allowing for any more downloads of the current Beta. Bottom line: it's really clear that Microsoft has been giving thought to alternative and innovative mobile user interfaces lately.
Deepfish is a new type of mobile information browsing experience, aimed at preserving the rich layout and full form of documents on mobile devices while providing novel ways of effectively navigating that content on small screens.
