I am hoping to use my Surface RT as a light-weight, extension to my work desktop. I love the portability and long battery life. I will quickly upgrade to the Surface Pro when it is available so I am 100% compatible with my Windows 8 and Office 2013 desktop. I'm really looking forward to running Outlook and Live Meeting on the Surface Pro.
I would initially use this for work because we have a piece of software that manages mobile devices but it is limited to Apple products at this time, it would be great for testing here to get our stuff working with Windows RT.
After that I imagine I would use it for a little bit of play since I have not used a Windows mobile device yet and have been an Android centered for a few years now.
I have to admit this thing looks pretty nice and I am really interested in what it can do.
