I want to buy a new eMac and there are none left that have Panther in my country (Japan). The problem is I do not want to pay for M$ Office again as the new eMacs have Tiger. I hate being forced to buy that crap. I do not use Excel for very sophesticated stuff. But I need to be able to open Excel files and create spreadsheets that can be opened by Windows Excel users. Will Mariner Calc suit my purpose?
