Ram
I was excited when they started with the hardware upgrades, saw good things coming. But...
2G RAM is a deal braker. My BP G4 has 2 gig RAM - and is 5 years old (thats in IT an eternity), my 3 year old 1st gen MBP has 2 gig RAM... For a premium laptop that is not enough any more. This is not a size question and it is not so much price anymore... So, why?
