I've been thinking (rare, I know), and I *really* like that Honeycomb is built to avoid physical buttons on the front. I'm fully expecting this to spill over to handsets in future versions of android. It is now possible to have devices that need no buttons at all on the front of the device. Imagine a Galaxy S3 that is all screen and an ultra-thin bezel -- with that beautiful SAMOLED technology, this would be a sight to behold.
