I've had my i5 for about two weeks now. I've transferred many large files over, installed multiple processor hungry programs, ran multiple programs at once and it still has not crashed!! 
This is my first Mac so I'm pretty blown away at my computer not crashing on me, I do not take this pleasure for granted. When I installed Windows 7 on my PC a few weeks earlier, it crashed several times after a clean install.
