I'm planning to buy Apple MacBook Air MD711HN/A. I would like to know whether its compatible with Windows 8.1. Is it possible to have a single OS (Win 8)? I use Windows very frequently and travel a lot.
Yes. Boot Camp works with Windows 7 and above, including Windows 8.1. You can remove OS X and have a single partition for Windows, although you will not be able to do firmware updates.
