Actually, I'm not as smart as you think ;)

There needs to be some extra checking, possibly with the carry flag.

For example:

0x70000000 - (-0x70000000)

would be less than zero as a resulting integer.

But it would work with shorts or bytes!

In any case, the example was bad, the point that which is better depends  
on the situation is still correct.
