Since a 32bit OS cannot address more than 4GB, the hardware addressing must also occur below the 4GB limit and that uses up some of the available addresses meaning they cannot be used to address memory.
I agree with you about XP Pro, although for my home system the only time I notice a limitation is when I want to work from home. I have Vista Business on a laptop and haven't had any issues with it, at least no more than switching between any of 3.1, 95, NT4, Win2K, XP.

Awesome explanation! See... this is why I want to see a sub-forum instead of a colossal thread.
So the bottom line is, if you want to use 4 Gb of ram, get a 64 bit system (hardware and software)?
