Dude, your picture looks off center. Can you please take one that is not at an angle that favors the new MBP? Also, are both brightness settings at maximum? Thanks.
To the OP, you should get back $500 or an upgrade to the new MBP. It's your right. PS, in the future, buy from apple.com
I won't speculate on the angle of the photo, however in my experience with having a new MBP and comparing it to the previous model, you have more useable viewing angles with the new model than the outgoing. I am not thrilled with only having Glass (read glossy), but the panel itself appears to be superior in this regard on the new model. Would be nice to see someone make a quicktime VR with two Macbook models side-by-side for comparison.
I don't really have a recommendation for the OP, but I don't agree with ggjstudios observation of only cosmetic changes. Having solid aluminum with no plastic gasket framing it, makes the new model far superior in overall structural rigidity. The old MBP was far superior to any Dell or HP in this regard, however it does not match the new unibody models. There are also more and more benchmarks showing that the new models have superior graphics cores, and offer some features (offload of h.264 decoding) that currently is only supported by the new models. CPU to CPU the differences are not worth mentioning, but if you do graphics intensive work, the new model may be better equipped to make your work time shorter overall.
