Before I can somewhat accept Tiger, first we have to fix Tiger's (and Panther's) Classic, which is broken and horrible, compared to Jaguar's Classic (and earlier). I keep wondering if one can just paste Jaguar's Classic on Tiger, fix permissions etc., then perhaps edit a .plist file or two to prevent Tiger from complaining, and voilá. Or maybe it won't be so easy.
Even then, it ain't no Mac OS 9.
What about creating an OS 9 app called "Neo Classic" to run OSX apps instead?
Not that anyone would want to invest the time to do that.
...Right?
