Intel might release quad core chips for laptops by the third quarter..check full article here link so i guess all upgrade hopeful's might try to wait..
At least just by knowing that it might be available by next year or so..makes me more patient in getting a new mobile mac and i'm just going to wait for snow leopard as well..still love my Penryn 15"
i wonder if mac pro will have a setting like alienware m17 in the near future... crossfire videocard. that would be a cool upgrade.
