My answer is still the same though: If you're going to upgrade the HD, you might as well go all the way to 7200 RPM. The wattage isn't that much more, and the cost of the HD is more than made up in the performance. I've had this done in my Albook, and it's been worth it. Get someone to install it for you; doing it yourself will waste a whole day.
