Am I addicted?

I originally bought my Macbook Pro on craigslist.com. It was my first one and since it was faster than most PC laptops, I didn't realize it was the 2006 model. It's battery only lasts 2 hours (which it has started dying within 10 minutes even after replacing the battery, wonder why guy sold it) instead of 8. Now I want new Macbook Pro. Funny!
