Microsoft’s Windows RT meant for tablets is a cut down version of Windows 8 where you can only install apps from the Windows store. Windows RT comes pre-installed with Office 2013, but it does not feature the Outlook 2013. Windows RT users had to depend on the default email client.
But things have changed now, Microsoft has announced that with Windows 8.1 Update, Windows RT will receive the Outlook 2013 RT. This means, if you already have a Surface RT or a Windows RT tablet from any OEM partners, you will be able to get Outlook 2013 RT free of cost. You can manage your contacts and appointments better with Outlook 2013.
Outlook 2013 has been the best version of Outlook so far with best clutter free interface and more usable. Morgan Stanley research study found that 61% of people shopping for tablets consider Microsoft Office to be the single most important software feature and now with the availability of Outlook 2013 in Windows RT along with Office 2013 RT applications including Word, Excel, PowerPoint and OneNote, the experience is going to be a lot better.
Along with this, there is also improvements to Surface touch and type keyboards and this will be rolled out in a week.
