- Apple has done studies showing that the vast majority of Mac programs
- spend a large part of their execution time in System routines, I
- forget the % but I think it was ~50%. Guess what, you don't have to
- emulate any system software. Any time spent in the system software
- will run at full speed on a PowerPC in 68k emulation mode. Your
- current software is not going to be junk, most of it will work at
- least as fast as your current machine. And native PowerPC code will
- run many times faster.
