I am/have been a long time PC user and used Microsoft PC based applications extensively with variable results. Having recently dipped my toe into the Mac world I needed to obtain the MS Office application for Word, Excel and Powerpoint applications that I could shuttle back and forth to work where we are mired in PC's. I was really surprised at the commonality of the MS Office applications bewteen the two operating systems and the seamless interoperability of the files. The stability of the applications on the Mac platform is excellent and have yet (knock on wood) to have one of the applications crash or hang. Overall I would highly recommend the Mac MS Office application due to it's interoperabilty, fast learning curve and unparalleled stability.
