Hello, I am currently in the market for a Mac Book. I am interested primarily because of its capability to run both Mac and Windows simultaneously. However, I was wondering if the Mac based Windows is able to execute and install Windows based software and whether it can read Windows only CDs when it is under the Windows mode? Also I was wondering if anyone knows how they install both systems and whether it has negative influence on computer's ability to function properly? Thank you! Any information will help me make my final decision!
