2003? The "Aluminum" era of Powerbooks had cases that were total crap. I owned three of them (one G4, two Intel) and the worst part was that the optical drive mount would go out of alignment and it couldn't eject disks. Also, the skin oils in the palms of my hands etched the surface of the case like crazy. They were just bad, but I had a "Pismo" G3 from 2000 that was even worse about falling apart inside.
I'm currently using a "Late 2011" 17" MacBook Pro that I got in 2012 when Apple announced that they would be discontinued. The "Unibody" cases are much more sturdy. Mine has been through a lot of bumps and scratches, and the worst thing that happened was I dropped it on the corner by the power plug and the video connector came loose and had to be re-seated. The second worst thing was after four years, gunk accumulated under the edges of the trackpad and it wouldn't click properly anymore. I fixed that too. (I'm aware that some of that series had GPU problems that were probably due to lead-free solder, but not mine.) Quad i7, full-HD 16:10 LED-backlight display, upgraded to 16GB RAM and SSD. It's been a fucking workhorse. I still feel like all the Retina models so far would be a downgrade.
So "Crappy model of Powerbook is crappy." Who'd have thunk it?
