I just ordered my 20" online and the sales rep highly recommended that I buy Microsoft office for mac. His reasoning was that I would need it to open any word documents that other pc's would email me. I then asked the store rep and she said that I could open it in Pages and I would only needit for powerpoint etc. I don't know who to believe. I already ordered it....so I need a quick reply if I need to cancel. Any help wouldn be appreciated. I'monly paying 144(military discount). Thanks.
