Ever since I got my Surface RT, with Windows 8, I have two (and only those two) things I got annoyed by:
1) No Windows Live Writer.
2) No Outlook.
For my first annoyance I quickly found alternatives, so not problem there…
But I do missed my Outlook… I love my Outlook and there wasn’t any.
So, there was a new Operating System by Microsoft for tablets yet it had no e-mail client?
Well, they solved that in Windows 8.1 RT ! 
Windows RT 8.1 comes with Outlook… and even more impressive: It will be free! #MeLike
