Just ordered a refurbished 15" 2.6Ghz, rMBP with 16gb RAM and 512GB SSD. I've been through a 15" 2.3ghz rMBP with 8gb, classic MBP 15" and a fully loaded air, but the 8GB always worried me considering I plan on using it for the next 3-4 years. Can not wait for it to show up. I now have ample space for OSX, BootCamp, gaming videos and pictures. So glad I switched back after years of Windows based PCs.
