I think iFixit does an amazing job of being accurate, given that the guides are written based on physical tear-downs. As a small-time mac technician, I am eternally grateful for the unlimited use of free, comprehensive guides. Instead of complaining about free advice, you can easily submit an edit to the guide if it is truly in error. The bottom line with Apple products - they are impeccably engineered, although have some annoyingly tedious steps because of the compact nature. They are build to last, but BE GENTLE!!

You can actually replace the keyboard alone fairly easily! I don't know why everyone says you have to replace the whole top case, because if you've got the guts to go this far, you might as well just peel back the illuminator cover and get to work pulling all those tiny screws in the keyboard... Just be careful when peeling up the black adhesive keyboard cover, because you will need to replace it. I used the edge of the ifixit Sesame tool (very thin flat metal opening tool) to carefully slip under any bits of adhesive, and had the keyboard exposed in no time. Also be careful because the clear plastic sheet is actually the keyboard illuminator. Once under all that, it's a mere 50 or so tiny screws, 2 screws in the power button backing, and you've got the keyboard out. Use a magnetized #000 phillips, it will make life much easier than anything else.
