I didn't mean to make it sound like there was nothing to it...it is a tedious job that needs some fineness. So those are very
good points. I just hate prying anything apart...worried about damaging the case, etc. Having been a gear head as a kid I learned that forcing something rarely ends in a positive outcome. But in this case, that's how it was designed.
Upgrading the memory and/or hard drive doesn't void the warranty (as long as nothing else is damaged) so I'm at a loss as to why on earth Apple won't just put four screws in the bottom. I guess it keeps the idly curious out, but...
So yes you certainly have to be careful with the wires, don't lose the little antenna springs and remember where the one longer screw is located that holds down the drive assembly. (And aren't those four screws easy to get to? NOT!)
In any case, following the video makes it fairly painless, and anyone comfortable working on a computer or other small CE products should be able to handle it. Here's some pretty good info if someone wanted a printed set of step-by-step instructions as well:

But agreed, if it doesn't look like something an owner is up for, by all means have a professional do it.
