Half the apps pre-installed on the Surface RT launches in the classic desktop interface, most notably Microsoft Office, where the smaller user elements do not play nicely with the touch interface.
From AnandTech's review just typing into Office takes 50% CPU.I had totally expected Microsoft will get Office right - touch friendly, not relying on classic Desktop and relatively bloat free. If integrated well with the tablet interface it would become a better productivity machine for Enterprise users than competition's offerings.
With what is being said of Office RT, I don't see what the selling point of Surface is - It is Windows but can't run Windows apps, it is a tablet but needs to switch to classic to run a so-so version of touch-unfriendly Office (Do I get Outlook with it?).
May be it will be a better story with Surface Pro.
