You can tell by the title, Why bother? The sad state of Office 2013 touch support, pretty much what Ars thinks of the new Microsoft Office 2013. If this was it’s state on iOS devices, I could understand it, but the review is based on it’s performance on Windows 8.
This shouldn’t surprise anyone, as Office 2013 doesn’t look a lot different in layout (the theme looks very different, the new “flat” Windows 8 desktop look), and with it’s love of lots of menus, buttons and scrollers, you don’t have to be a genius to see it’d need basically a full rebuild and UI re-do (IMHO).
Thanks for the pointer from The Loop.
