Yeah, but can you restart app? can you terminate app inside Olly?
can you pause and continue?. You can not use Olly to debug another app, you must exit.
App crash when you run it with Olly too.

System debugger is a SO internal installed debug (it runs at boot), like WinDbg from M$. Procees debugger is like Olly.
