Hi Guys ! Finally time to upgrade the MBP it's been 2 years, so the model I have has the following specs: MacBook Pro (13-inch, Mid 2009) 2.26 GHz Intel core 2 Duo 2 GB 1067 MHz DDR3 What are you thoughts on the i5 vs i7 dual core (13") and the quad core (15") I usually use my MBP for basic things and carry it around the house and when I travel. I do notice on my current MBP that I run out of desktop space so the higher resolution would be nice. Though $600 for more desktop space seems a bit steep. Also once I buy my new MBP I'd be looking to sell my 2009 model, what would a fair price to sell it for ?
