Yesterday, Lifehacker had an article by Adam Pash about adding more RAM to a Macbook Pro. They also setup a the whole experiment along with some playing with a camera to film the whole process and provide a video. Nice setup Adam.
I agree with Adam and some of the commenters who commented that upgrading RAM is a user-installable component but not 100%. My only and the biggest concern is that the process was presented without informing the readers about the most important precaution - discharging yourself off any static electricity. Several components in a laptop (especially RAM modules) are sensitive to static charge and if care is not taken, you could end up hosing your system or the brand-spanking-new RAM modules. I haven't seen a RAM module till date whose manufacturer offers replacement of fried-RAM modules due to static.
So, Lifehacker and others who want to upgrade their laptop/PC with new RAM, do your homework and take proper precautions before you open your computer. If you are still not confident enough, ask an experienced friend or even pay a technician to do it rather than frying something in your system and ending up spending more than you saved!
