The new Outlook style, while attractive, concerns me a bit from a training standpoint, but the only thing I’m really disappointed with is that this preview version doesn’t include a feature for embedding web video in PowerPoint, which makes me worried we won’t see it in the official release. They have web video embedding for WORD but not PowerPoint?? What?! I also hope there will be some work done to make Office more tablet/touch-friendly at release.
Other than that, I’m intrigued and would love to try these new apps for myself.
