I have been reading of some horror stories about how Ebay only protects the buyers. Lots of scams out there. Thinking about selling my 17" I7 AG laptop for the new Retina. I have Apple care till June on it so I thought now maybe a good time to get the most money for it. What concerns me is that the new Laptops dont have an Optical drive built in and also the with the Hi Res display do you have to kick up the Mag. to read websites etc.? I am getting older and on my 17" I normally hit the + button once to increase the page views. Is it a better deal to just get the 256 gig SSD and upgrade later yourself cheaper than dishing out the $500 extra for the 500 gig drive? I like my 17" but I probably could do fine with a 15.. Any thoughts?
