You can map SkyDrive as a network drive on Windows RT (Google it). Anything saved on other computers shows up there (but has to be downloaded to be accessed) and you can also save files directly there. If you have a SkyDrive file open and you click "save", it will upload to SkyDrive which I like. It also feels more familiar to me so I like it, but it's not quite the sync you get with the desktop/x86 app.
