Not only did Microsoft bother to give us an early warning on the launch of their new mobile application ZenZui, but they created this YouTube video so lazy bloggers like me didn't even need to explain it.
I will anyway: it's a zoomable user interface for mobile phones that came out of Microsoft Research - it's now funded by Microsoft’s IP Ventures and running as an independent company.
Kayak.com, OTOlabs, Traffic.com and others have signed up to test the new product, which will be monetized through sponsored "tiles" (see video). Just don't tell them it looks like the iPhone interface. ;)
