I've been delaying my purchase for awhile now. Refurbished MacBook Pro 2.53GHz Intel Core i5 with AG Hi-RES screen or Refurbished MacBook Pro 2.66GHz Intel Core i7 with Glossy screen for almost the same price. Of course there is the Refurbished MacBook Pro 2.66GHz Intel Core i7 with AG Hi-RES screen for $200 more. Which would you recommend. I have a 2008 MacPro as my main computer, but need a laptop for portability. If I wait longer, I might end up with the 2011 MBP.
