Apple is seriously lacking in the quality control department these days. They should take some of that $15 billion cash reserve and spend it on QUALITY CONTROL.
I told my sister to SKIP the 10.5.1 update because I'm afriad her Macbook keyboard will start freezing up on her, then I'll never hear the end of it. (I convinced her to switch).
Hopefully 10.5.2 will get Leopard further away from its beta status.....
