MACBOOKS HAVE ISSUES WITH RAM AND FAULTY NVIDIA GPU?

I thought Macbooks were the best notebooks ever? I guess even the best have their problems as reports of RAM and NVIDIA chip problems continue to surface about Apple's new Macbook systems. Apparently installing 4GB of DDR3 RAM from Apple or third party sources is causing the Macbook's and the Pro's to freeze up. The problem can be fixed by dropping the RAM down a notch to 2 or 3 GB.

In terms of the NVIDIA chips, we're also hearing that the new MacBook Pro's NVIDIA 9600M GPU suffers from "bad bump" problems which troubled the previous versions of the system. This causes black screens, video errors and a whole host of other problems.

Its not sure if this is affected by batch or if this is a bigger problem. Either way lets hope Apple fixes this before they begin to get the bad rap Microsoft is used to.
