The best part about Sky Drive is that you don't need to be limited to certain types of media. It's even great for backing up important documents. Since you can access these files from another computer, you can store papers that you have to print off such as essays, spreadsheets, or hand-outs. The sharing aspect is great, because if you have something you want to show a friend, all that person has to do is access the file on your Sky Drive. No worrying about having to upload a file through e-mail or a messaging program. You always have full control over what you upload, too. If there's something you want to make public or private at any time, you can do so. As mentioned before, Sky Drive is free. If you have a Hotmail account, a Windows Live account, MSN, or Microsoft Passport, then you already have access to Sky Drive. If you don't, then all you have to do is sign up.
