I have ordered a Macbook Pro and am waiting in line with everyone else. I always know that whatever computer I get there will always be a much faster computer waiting around the corner. 64bit chips however seem different and have got me trying to decide if I should cancel my order and wait. My questions are this: 1. I hear that 32bit chips can run 64bit operations but not as efficiently. Is this true and if so does this mean that my computer won't be obsolete any quicker than the next? 2. Will there be 64bit only software that a 32bit chip would not be able to run efficiently? 3. Will the resell value really drop or is this just specuation? 4. If Merom chips can be "droped" into a yonah socket and the macbook pro's chips are soldered on can they be unsoldered and replaced by a professional at a later date? 5. Will 32bit suport be dropped quickly because 32 bit intel chips were only made for 6 months? Help me make a decision. I'm not a professional who needs a high end for work however I would like a fast computer with a decent graphics processor that will still feel speedy after two or three years. Somthing that can play modern games if I want to. I realisticly wont buy another laptop for proably three or four years.
