Got the 200GB extra space on Skydrive with the Surface 2 here. Great stuff. Before Windows 8.1 I wasn't so keen on using Skydrive, mainly because it wasn't a great integration. Everything changed now with better support...
But here comes the thing: Skydrive doesn't support P2P and if I want some of that content to be available on a new PC it will then download from the servers instead of getting from another PC in the same LAN.
For example I want photos to be available offline - also because if I want to look at photos I want instant access. I put my photos on Skydrive, all 25GB of them but now I want to blast my laptop and reinstall Windows 8.1. This means downloading those 25GB back, even though I have those files in another PC in the same LAN.
I am thinking better to stop synchronising this to Skydrive and keep it local only (don't worry about backup, I have a copy on a home server, plus Crashplan backup plus Dropbox - which does support P2P).
A shame really.
