images (17)Microsoft announced that Outlook 2013 RT will be coming to Windows RT, along with the Windows 8.1 update. Sales of Windows RT tablets like the Surface RT have been underwhelming thus far, but Outlook will change that.

When the Windows 8.1 update comes to the Windows Store later this year, Outlook RT will join Word, Excel, PowerPoint, and OneNote as a free app on Windows RT systems. That is huge news in general, but it’s particularly intriguing for business users.

The Surface RT (and Windows RT tablets in general) is a decent tablet, but it’s not a great device for business computing. It has distinct advantages over its Surface Pro sibling–it’s thinner, lighter, cooler, quieter, and has significantly better battery life–but it can’t join a Windows network domain.

With the Windows 8.1 update, it still won’t be able to join a network domain, but the IT and BYOD management features in Windows 8.1 make it much more business friendly. The addition of Outlook is the real game changer, though. The default Mail client in Windows 8.1 is no match for Outlook, and business users need consistency between the tools they use on their primary PC, and the apps available on the Windows RT tablet.

Smaller Windows tablets are expected to launch later this year. The small size, combined with the features of Windows 8.1 (and the inclusion of Outlook) will make Windows RT tablets very powerful business tools.

Earlier this year, Nvidia CEO Jen Hsun Huang told an audience of financial analysts, “If Outlook were to show up on RT, my life would be complete,” adding, “I am one Outlook away from computing nirvana. Outlook god, please…”

Why does the CEO of nVidia care? nVidia has a vested interest in the success of Windows RT because it makes ARM processors that are used in some Windows RT tablets. Success for Windows RT means more demand for nVidia processors.

Office is a powerful carrot that Microsoft hopes will lure customers over to Windows tablets–be they Windows RT or Windows 8 Pro models. The addition of Outlook is a significant advantage for Windows RT tablets, but even if Windows RT doubles…or even triples its market share, there will still be a massive audience of iOS and Android tablet users left in the cold.

According to an alleged internal roadmap document leaked a couple months ago, Outlook RT was not supposed to be ready until late 2014. That roadmap also suggested that Office for iOS and Android might also become available around the same time.

It’s possible the leaked roadmap was simply wrong. Assuming it was legitimate; the accelerated availability of Outlook RT suggests a spark of hope that Office for iOS and Android will also be available earlier than anticipated.

If Microsoft is working on iOS or Android versions of the Office apps, it’s still being coy about it. The official response was, “We have a great Office experience on Windows 8 tablets.  For iPad and Android tablets, people can use Office Web Apps.”
