Just got my refurb 15" 2.53 i5 antihighres today. I was expecting a 500GB 5400 drive and 4GB of RAM, or so the description stated. Just system profiled it. 8GB OF RAM! That's awesome. That's a $200 upgrade in apple dollars. I know it would have only run me about 75 bucks now but I'm still jacked about that.
