My wife and I are soon purchasing MacBook Pros for the both of us. Both 15" models and I'm going to get the beefier of the two for myself as I have quite a desire to get into video editing - especially with kids soon on the horizon. I've been reading as much as I can lately about Macs and it's my understanding that the new version of OS X is coming out in October. Ideally we'd like to get these powerbooks before October. Any reason why we should wait besides the obvious that I won't have to buy it later?
