That might be exaggerating somewhat, Java runs between your library of apps and Office but the actual store is HTML and XML based; on the other hand why you need an app store for office or what these apps will be is a bit of a mystery.  The Register also noticed a rather poorly thought out feature, your controls recede into the background when you are working on your document which can make finding the right button on the ribbon a more difficult task than it should be.  On the plus side the controls are more spaced out making it easier to use with the touchscreen input capabilities of Windows 8 and who wouldn't want to build an Excel spreadsheet from scratch using a touch screen keyboard?  This release also marks a serious effort by Microsoft to make Office applications mobile, not only for Surface but iOS and Android as well, so there is that.
