I like this site. They teardown a bunch of products. People can send in their own tear downs. Its set out nicely, and can satiate your curiousity about how the insides of your thingy come together in a neat little package.
The gave the new MacBook Pro a 1/10 for repairability. You cant upgrade the memory or the HD. The monitor is a clusternut of assembleness. The battery is glued to the computer (lol what?) And you need special screwdrivers to remove screws. Have fun!
Even though Apple seem to have gone backwards in the repairability side of things, its still impressive how they fit everything together so nicely. Too bad they make it impossible for noobs like me to fix em.
