Hi all, I'm planning to buy windows tomorrow for my MBP 13" (I bough it last May). The prime reason is the use of Microsoft Excel..I've been attuned to using the shortcuts on Excel (PC) for years and really need to be able to navigate it better. I have a few questions below: 1. I'm a light user (no gaming, just word/excel/homework/internet surfing) - would you advise Bootcamp or parallels? 2. If I do install my windows CD on bootcamp, and I change my mind and want to use parallels, can I reinstall windows?? Do I have to? I don't think the CD can allow me to install twice. 3. Anyone who has the same adherence to Excel shortcuts can comment on the ease of excel with windows on a mac? do I need an external keyboard? Thanks so much!!
