To all the MacCook Pro 15 owners... has Apple fixed all the technical issues with this laptop - things like the RAM (2GB and 4GB) and the display freeze? I would like to buy a MacBook Pro but unclear as to whether the issues are resolved. Also, does the 17 MBP have the same internals and thus likely to suffer from the same issues? I am literally about to press the buy button on a Dell Studio 16 laptop even with the Vista issues, but prefer to make the switch to the MAC. Your advice is appreciated.
