Would it make sense to buy a 15.4 inch macbook pro base model with the 500GB hdd and 2.3ghz I7 at this point in time?? I have over $1800 some to spend at best buy, and I was looking at my options, and I see I could also swing the Retina pro 13in, but I was looking at the display models, and two of them had the image retention/ghosting issue. I was also considering waiting for maybe a higher end windows 8 touch screen machine, but worry about issues with the touch screen and such. I guess my problem here is, I keep wondering if spending $1800+ on that 15.4 inch macbook pro is a good deal for what it is. Thanks for any input.
