Hello all I am new here and cyber-dumb. I bought a Mac because I hated every PC I've owned. So far I am glad I switched. The only issue is my daughter, a HS freshman, has assignments that require PC type programs such as power point. I downloaded a trial of iworks but she says it still doesn't quite work the way MS Office does. I am very hesitant to add any MS programs and mess up my Mac. The guy at Best Buy said if I download (or is it upload?) Office I will have the same virus dangers as if I had a PC and urged me to buy iworks. So that is when I tried the trial version. What is my best route?
