I'm currently looking to replace my Macbook Pro that I bought in the spring of 2006 with a new model. I've been looking at the 15" size and I was wondering if the extra .2GHz, 250 GB and updated video memory is worth the extra $400. I tend to use my Pro for video editing, some graphic manipulation, and gaming from time to time, so I'm definitely looking for a high end laptop, but I'm not sure if I need to spend the extra cash. Also, should I wait for the next model to be released? The buyer's guide on this site said I should, but it hasn't been updated since March. Any and all suggestions would be greatly appreciated. Thanks.
