just got my new macbook pro (prev gen though), not the new unibody. got such a good deal with a 320gb hard drive 4gb ram etc that i couldnt pass it up. anyway, this is my first mac and of course i have many issues but that is actually not the point of this post or question. here is my issue. it seems like the regular macbook closes with a m agnetic something or other and closes so nicely, while my macbook pro uses some type of latch system that to me doesnt seem like a good build. are there known issue with this or does it hold up to being closed and opened say 3-4x a day every day?
