Let me preface this by saying I plan on getting a Quad Core iMac or mac pro if the former does not get announced at MWSF 2009. Ok, so I have a new unibody MB and I love everything about it except the screen. I would not say I 'hate' it, but compared to the MBP screen its terrible in my opinion. Basically, my question is for only $350 (for my instance specifically) do you think it is worth it to upgrade to the 2.53, 4GB, 320 (ill add my 500GB HD in)? If i get the MBP, I'm getting the top end for the video card specifically. I can live without the video card in the MB, but the MBP would be nice since I could play FSX on the go. I am leaning towards saying of course it is worth it since it essentially has the same battery life and for a 15" machine is as portable as it gets. Is there anything I am failing to recognize here? Thanks for the help.
