..well, since Apple switched to x86, they're really using the exact same cards as anyone else. The same goes for wifi, sound, processors, bridges, etc. Because the components are cheaper, and work better than in- house special orders.. But I assume they will give you support if something breaks down, and that it should be easy to fit the laptop with the parts, and so on. ..or then again, maybe not. If you have to send it in somewhere so you won't void the warranty. And can't really open the laptop without special tools anyway.. Dell gives you that kind of service too.

In any case: basically - if you can't wait for a few years until a more lightweight laptop/MID turns up with a different architecture - some sort of RISC, or a SOC solution of some sort exploiting parallelism to save a significant amout of clock- cycles, and power for the mainboard and peripherals - .. that might be years, I guess... even if Nvidia has actually made one of those already with their Tegra chip.... then buy one of the smaller laptops with an intel Atom setup. It won't be able to cut&paste videos as if you were seeing the carefully sized and cached examples in the Apple demonstrations. But it's more than enough for anything that doesn't involve...er.. production of movies while you're waiting for the elevator, and so on.
