I'm new here and will likely be making the switch from Windows to Mac, at least for my notebook, in the next week or so. I am looking into buying the base model of the 13" MBP of the Apple website. I am a university student studying Business, and am very dependent on my laptop for completing reports, essays, and assignments. The university I go to is mainly Windows based, so it is important that I will be able to work on the same files on my MBP, as well as on the computers at school. I've never used a mac before and my main concern is compatibility with windows, especially the Microsoft office software. I need to be able to work on the same file on mac and windows and also send files to others from my mac, to be opened in Windows. My plan is to install MS Office 2008 on the MBP, but I need to know first if there will be any issues with using the same files in mac and windows. I use MS word, excel, and powerpoint on a regular basis and need them for school. I am also wondering about the iWork suite. I can get this for $60 with my new MBP, is it worth it to have this as well, along with MS Office? The main things I will be using the MBP would be schoolwork, internet browsing and research, and possibly the Sims 3. Any suggestions, input, advice, etc, would be greatly appreciated! Thanks!
