Summary: Microsoft trickled out a few new tidbits about Windows 8 during CES this week, in spite of not yet having beta bits to deliver.

Microsoft execs made a conscious decision (months ago, I hear) against making this week’s Consumer Electronics Show a place to share key new Windows 8 bits or tidbits. That doesn’t mean, however, that the Softies didn’t discuss or debut any new Windows 8 features.
