I see where Best Buy is going to have the base late-2013 rMBP 4gb ram/128gb hd on sale for $1099 which is only $150 more than the open box late-2012 rMBP with 8gb ram/128gb hd I just bought. I have been reading reviews and most of the reviews tested the 8gb ram 256gb hd of the Haswell unit, not the base unit. I'm wondering if I should return my late 2012 for the new Haswell. My fear is that I am making a bad choice though as I would be going from my 8gb ram in my 2012 now down to the 4gb base model of the new Haswell. Anyone here go from last years base rMBP to this years base rMBP?
