Derek has a Mac and needs to use Excel, but has been told the Mac version doesn't handle the advanced functions. Leo says that's not true. There's different key strokes, but it's the same functions. If he has Windows, he could run boot camp and use the Windows' version of Excel. That way he doesn't have to relearn the software. The chatroom reminds him that he'll have separate partitions for both operating systems. He can use VMWare, and run Windows inside of the Mac.
