Just a quick post,
Microsoft have just released the new version of Office 365 as a preview online for a public trial of the home premium edition. This version of office is using the new metro interface and has a complete interface overhaul. It looks and feels much smoother and faster than previous versions of Office including Office 2010. You can give it a try yourself at this link. You will need a Windows Live ID (a hotmail account will do just fine) to login and trial the software and a small download is required to install the plug-in software to your computer.
Also, if you are yet to try Windows 8 you can grab the release preview version here. Metro takes a bit of getting used to but when you do it really is a pleasure to use. I recommend installing it direct to your computer rather than in a VM and the upgrade process from Windows 7 is the smoothest yet. You will also be able to upgrade from the release preview version to the full retail when it comes out in the next few week.
