I just love Apple. They come up with these incrementally different devices every couple of months and advertise them as entirely new products, making sure they crap out on you just after the point where their warranty expires, and then expect you to send them in for $$ repairs, or throw them out and buy new ones, because the obscure design makes it impossible to open the damn things up and make repairs yourself.

I'm not an Apple fanboy, but some of this isn't really fair.
Some of their devices (mainly the newer Macbook Pros) are relatively easy to work on, as removing the bottom panel gives the technician access to most of the internal hardware. The keyboard is a bitch to replace since it's underneath everything and the screen is one assembly, as opposed to having an LCD and the housing for it, but otherwise I'd say they're easier to repair than most laptops. The magnetic screws are the biggest nuisance, since they keep flying to different parts of the case when you're trying to screw it back together.
I've heard many a horror story about iBooks, but they're all but dead. iPod Videos aren't
terrible to open once you've done one or two, but the first time I opened one I found myself cursing Apple and their kin. With the iPhone/iPod Touch, it really depends on which generation we're talking about.
Again, not an Apple fanboy, but some of their designs are conducive to making repairs. Others are a nightmare. This is basically like any other company.
If you want to hate on someone for making their machines difficult to repair, we should start talking about Sony. If I had a magic button to make every Sony laptop in the world light on fire, I'd put a rock on top of it.
