On your forearms? You should not be pressing your forearms onto anything when you type or you'll give yourself carpal tunnel syndrome. Take it from one who knows! If the sharp edges discourage you from doing this, then more power to sharp edges!
I have not used a pre-2011 Macbook, though I did have a 2006 or so PowerBook. It was fine. My only complaint was that it get too hot to use with bare legs. This is one of the reasons that Apple switched from the PowerPC to Intel.
I haven't used a Magic Mouse. The idea of mouse with a touch-sensitive top seems like a great idea. I don't know how it works out in reality. I use a Cyborg R.A.T. 9 mouse. I love it. I also sometimes use an Apple Magic Trackpad, and I think that it is fantastic.

After a bit of browsing on Wikipedia and Freescale product pages, it appears to me that the mobile G4 chips typically used under 20 watts and had TDPs around 30. That's in line with (or below) the standard-power Intel chips found in the Macbook Pro from its introduction to current Ivy Bridge models.
There was also a low-power G5 processor that could, in theory have powered a laptop. Apple didn't go that route because it wasn't substantially (if any) faster than the G4, there wasn't a suitable northbridge, and the G5's idle power consumption was too high.
It appears Apple switched to Intel because there wasn't a suitable upgrade path for its laptops, not because then-current models consumed too much power or generated too much heat.
Yeah, the touch-sensitive top of the Magic Mouse is its main selling point. But that's all ruined by, again, the sharp edges. You can't tell me not to press my palm and fingers onto the mouse :)
