How about trying the new dual-boot (Mac OSX and Windows XP) computer lab? You can choose Windows or OSX! It is located within the Olin computer lab, behind the glass windows – in the back.
This mini lab (9 computers) is open to all students, everyday, all day. The only time that this computer lab is unavailable to students is when there is a training course being taught, and usually there will be signs to make you aware of any upcoming events.
If you are unable to secure a computer in the library during finals, please stop by and use this “unknown” lab.
