Too expensive?
As of 10 AM CST, there are two MBP C2D models and one C2D Blackbook, which I think has been sitting there a couple of days. It seems to me that only MBP's that last online are the more upgraded ones with a hefty price. I just bought a Refurb C2D MBP 2.16, which IMO disappears faster than anything with its $1599 price tag. Like it has been said, I think money is one of the main factors in these sales.
I think most people that can afford drop $2K to $2500 on a laptop dont really care about saving on a refurb and just buy new. Just a thought.
