I'm a high school teacher who is forced to use a PC at work but have an ancient Mac (2003 iMac lamp) at home. I'm patiently waiting for the Back-to-School sale to start (hopefully on May 24) while all of you get to enjoy your presents early;-) Because Office is installed on all of our machines at work I have most of my documents in Word, PowerPoint and Excel. I'm also running Office 2008 here at home on my Mac. Is it worth it for me to have Office installed on my new machine when I order it or will the iWorks suite allow me to transfer documents back and forth with little problem? Or should I install my current version of Office on my new machine? I've also heard a bit about Open Office but don't know enough about it to know the answer to this problem. Any help would be greatly appreciated!
