Hello, everybody! I'm considering to get Macbook pro for videoediting mainly. Almost everything is set, except one thing - do you think 64 bits will be essential for this kind of work year later? Maybe any comments on Macbook beeing futureproof? For how long? 2 years at list? More? Also - the battery thing, do you think there will be any ways of extending it's batery life (buying next-gen batteries etc..)? I'm new to apple and don't know about their old computers being compatible with newer hardware. Thanks!
