This laptop is called "asterope" and it is running "Ubuntu" rather than Windows. Here are some things you might need to know (and I can edit this document to add things when you have questions!). Beware that I had some power problems with this laptop so I don't know how long it will last. Turn it off when you aren't using it, and make sure you are using dropbox or google docs so that you won't lose anything if it does die!
This laptop has a touch screen and the screen rotates so you can sort of fold it up with the screen facing outwards. This might be surprising.
Whatever you want to do, press the windows key and start typing. Alt+F4 closes windows, Alt+Tab switches between them, I think those are both the same as Windows
