Microsoft Unveils New Office 2013 Preview, Download Now for Windows 7 and 8
You may think it is strange to host a big event to show off the new Microsoft Office, and you ask yourself, “Do people care, and do I care?” We think you should. The whole interface of the new Microsoft Office 2012 was heavily based on the Windows 8 Metro. The new operating system will be coming soon that will support tablets, ultra books, and some of the laptops with touch-screen based. Microsoft decided to go that route and make everything look more simpler and easy to use as if you were touching on the screen.
Now the new Microsoft Office 2013 preview is only supported on Windows 7 and 8. The bad news Microsoft has dropped support for XP and Vista. If you are Windows XP and Vista users, you should consider upgrading it to your liking.

Word from Microsoft Office 2013 Preview
You can download and play around with it. The preview version only contains Word, Excel, PowerPoint, OneNote, and Outlook. Microsoft stated they will be bringing more products for Office later in the future. It supports 32 and 64 bits machines and it is touch-capable software which means you can install this on your Samsung Slate 7 running with Windows 7 or 8. There will be business apps as well, Lync, Publisher, and Visio will be coming soon.

Here’s the full keynote of the new Microsoft Office 2013 preview and the video isn’t closed-captioned (Sorry, guys):
Remember, the new Office 2013 or codename “Office 15″ has been designed primarily for Windows 8 computers and will run on PCs as well as touchscreen tablets. You can download a preview copy and try it yourself. We are not responsible for any damages or loss of data. This version may not be for everyone. It takes time to master at the new Office 2013.
Here’s a better hands-on video by CNET and again, it is closed-captioned.
I installed the new Office 2013 on my laptop. It works excellent with the keyboard and the mouse but honestly the version is best optimized for the touch-screen tablets.
