I've always been underwhelmed by the decimal-point releases to OS X.

i.e. moving from 10.0 to 10.1 and now to 10.5.

It never really blew my socks away the way the move from OS 9 to OS X did. Then again, this IS a DECIMAL-point upgrade. It was never meant to be a radical departure from the preceeding OS.

I'd agree with the point that it is not a NECESSARY upgrade. But for me at least, it is definately worth RM509. But then again, as with everything in life, your mileage will undoubtedly vary....
