After debating between getting a MacBook or a MacBook Pro for the last few weeks, I went into an Apple Store and purchased a MacBook today (Backlit keyboard and upgraded the RAM to 4 gigs). If you are curious, my major concern was downgrading to a smaller screen from my PowerBook...but since the resolution is the same, I really shouldn't be too bothered. Moving on the my questions: 1) One of the biggest reasons why I'm upgrading is being able to run Windows. I occasionally need to use Excel and it's a lot easier to use Excel on windows than a mac. I'm curious what will give me the best solution to run windows? (Parallel, Boot Camp, Fusion (?)...etc.) My primary concern is being able to use the function keys in excel while in windows mode. Also, I'd prefer to be able to use Windows while in OS X. 2) What version of Vista should I buy? I've gotten recommendations to buy Vista 64-bit versus the 32. Thoughts? Thanks.
