I love my macbook pro. I've always been pro apple. This is my 3rd in the last 12 years, they are super reliable, my titanium laptop lasted me 7 years with multiple upgrades. I still use it as an extra.
The only thing I noticed with my best friends 2 yr old 13.3 white macbook is that the plastic around the keyboard towards the overall outer perimeter of the notebook has cracked and snapped off 80% of the way around. I don't think he abuses it, but he does take it everywhere. Maybe that's just the difference between the metal cases and the plastic.
As for ease of use and the OS, I love it, There isn't anything that my mac can't handle… though I do run parallels at least once a month for certain company webpages that can't be accessed with Safari or the last version of IE for mac. That's my only beef.
Welcome to the club, it gets addictive. As a kid we had an original macintosh. I also have an orginal shuffle, an 80 gig ipod, an ancient g4 and a mini on it's way download movies and watch them on the big screen! Enjoy!
