Looking at one locally, as I like the 15" form factor and would like an Intel computer with it. In any case, the one I'm looking at has 4gb of RAM and 100 cycles on the battery. I didn't check on the hard drive, but would likely put in an SSD anyway so this is irrelevant. It was running Yosemite when I looked at it, and actually seemed fairly useable and responsive(although I would likely downgrade to Mavericks). Cosmetically it had a few scratches but no signs of abuse or anything else abnormal. How would you all value this?
