I use skydrive regularly, with my windows phone and computer.

Its pretty fast, and because I was an older user, I get 25gb free.

Now as for the fact that you are on the wrong account, it is probably because Microsoft has unified its various services under the Microsoft account. So say if someone used your computer to login to Xbox live (or games for windows live), Hotmail, bing, MSDN, or any other Microsoft service, they are "Logged in", and thus if you go to skydrive, you will see their account.
