Unsigned? Not much.
The Unsigned Guide was created in 2003.
Having an unsigned integer means that the integer is positive, and not negative; literally, the integer is unsigned and assumed to be positive. The unsigned integer 8 is positive-eight, not negative-eight.
Yes, and given the lack of 64 bit software support, probably better, and you can use unsigned drivers.
