OS X will vary in its usage depending on how much total is available. Generally on a 4GB system, it will use around 768MB at a cold boot.

Liquid and computers don't mix. It might seem simple, but we see an incredible amount of people post here about spills. Keep drinks and other liquids away from your expensive electronics!

There is a glass overlay on top of your LCD panel. It would take an unusual amount of force to crack it. Pointing at it shouldn't break it, just exercise the same amount of caution you would use with any laptop.

"HD" is a measurement of screen resolution. Depending on the specific model, the resolution will vary. Most 15" MacBook Pros use 1440x900, which is better than 720P (1280x720). 1080P is 1920x1080, some of the higher-end MacBook Pros meet or exceed that resolution.
