Google Drive or Sky Drive?

My experiences with Google Drive and Sky Drive are very little. I have yet to use Sky Drive at all. Google Drive is more familiar just because of the familiarity I have with Google. I use Google as my primary Internet search engine, so I have played around with all they offer at least once. I have also used Google for the class Office Procedures and Technologies. I think I should start using these tools more frequently because of the many tools Google provides. Both Google and Sky Drive offer free space for you to save documents, presentations, spreadsheets, and more. I usually just carry my USB drive with me at school which is probably the reason I have not used the services both drives have to offer. Maybe I will start using Google Drive for assignments at school and use my USB for assignments completed at home.That might be a hard habit to break though.
