Although I'm sure it does happen having a computer fail straight out of the box is rare, I wouldn't worry too much about that.
True... Just reading all the reviews and whatnot and learning what problems others have had, makes me a tad paranoid! But for the most part even if there is a defect such as it saying you're diving while you're not or such, it will still be usable and I could send it in when I return home.
Still very torn between these two. I'm very indecisive to say the least!
