With all these HTC models getting their brains rearranged to run Android, we're starting to wonder: just how necessary is the Dream? Don't get us wrong, we're pretty amped to see what kind of amazing hardware HTC's crafting to officially debut the consumer-ready cut of Android to the world, but there are plenty of very capable handsets already in the field -- and the Touch Diamond and Touch Pro should both be more than willing to donate their bodies in the name of science when the time comes, too. The latest model to get an Android port is the Polaris, also known as the Touch Cruise in production trim. At this point, the ports are still pretty raw and the level of functionality or spit and polish probably isn't what you're used to with the native WinMo installation, but they're getting there -- and considering that Android itself still has plenty of work remaining, it's an impressive feat and a promising sign of things to come for owners of older devices. Let us know how it goes if you're brave enough to give it a shot, y'hear?
