I bought my new 15" MBP (low end) about 2 weeks ago. I've been using it gently, only at home. But already, I've once had a problem with my camera not working, Photobooth freezing, and just now, the whole computer freezing while watching a youtube video (the video kept on going, as I could tell from the audio, but my entire screen was frozen and I couldn't even get the cursor moving). I know none of these are major problems, and forcing a shut-down and rebooting fixed the problem. But is this normal?! I feel like for what I've paid, it shouldn't be having problems at this stage yet, no matter how minor.
